ATEK vs Onset HOBO

See how ATEK compares to the competition

Onset HOBO Strengths

Research Community Standard

The HOBO brand is a de facto standard in academic and environmental research. Since 1981, HOBO loggers have been cited in thousands of peer-reviewed publications, making them the most recognized data logger brand in research institutions, universities, and field science applications worldwide.

Affordable Entry Price Point

HOBO loggers start around $60 for basic models, with Bluetooth MX-series units ranging from $60-$250. This pricing makes Onset accessible to grant-funded academic budgets, small research labs, and organizations that need dozens of loggers without a large capital outlay.

Bluetooth Ease of Deployment

The HOBO MX series offers Bluetooth wireless communication with smartphone-based setup and readout. Non-technical researchers can deploy and collect data without IT infrastructure, software installations, or network configuration — ideal for field research and temporary monitoring.

Onset HOBO Limitations

Research-First Design, Pharma Compliance Bolted On

Onset's core HOBO loggers were designed for environmental research, not regulated industries. The InTemp line was created as a separate product to address pharma cold chain needs. While InTempConnect provides FDA 21 CFR Part 11 compliance with electronic signatures and audit trail capabilities, it remains a separate platform from HOBOlink, creating operational complexity for organizations managing both research and regulated monitoring.

Two Separate Platforms and Product Lines

Onset operates HOBOlink for HOBO loggers and InTempConnect for InTemp CX-series loggers as separate cloud platforms with different interfaces, different hardware, and different feature sets. Organizations monitoring both research and regulated environments must manage two distinct systems.

USB-Dependent Workflows for Most Products

Outside the MX Bluetooth series, most HOBO loggers (UX100, UX90, U-series) require physical USB connection to a computer running HOBOware desktop software for data download. This manual workflow creates gaps in data continuity, delays in excursion detection, and compliance documentation challenges.

Why Choose ATEK

Why Organizations Choose ATEK Over Onset HOBO

When Dr. Dave L. MacFarlane founded Onset Computer Corporation in 1981 on Cape Cod, Massachusetts, he created something the research world had never seen: affordable, deployable data loggers that academic budgets could actually afford. The HOBO brand became synonymous with field data collection, cited in thousands of published studies and deployed in universities worldwide. After LI-COR Environmental acquired Onset in April 2024, the company gained environmental science credibility but maintained its research-first DNA. For organizations that have outgrown research-grade logging and need continuous, compliant monitoring, the question is whether a platform built for field scientists can deliver what regulated facilities require — or whether the InTemp pharma pivot bridges that gap.

Understanding Onset HOBO

Onset Computer Corporation has operated from Bourne, Massachusetts (Cape Cod) since its founding in 1981. For over four decades, the HOBO brand defined the affordable data logger market. HOBO loggers became the default tool in university labs, ecological research stations, and building energy audits — anywhere researchers needed temperature, humidity, or light data without enterprise budgets.

The product portfolio has grown into distinct lines: HOBO MX-series (Bluetooth wireless loggers for research), HOBO UX-series (USB-download loggers), RX3000 weather stations, and the separately branded InTemp CX-series designed specifically for pharmaceutical cold chain monitoring. Critically, these product lines operate on separate platforms — HOBOlink for HOBO loggers and InTempConnect for InTemp devices — with different cloud interfaces, different capabilities, and different compliance postures.

LI-COR Environmental, a Lincoln, Nebraska-based environmental instrumentation company, acquired Onset in April 2024. The acquisition brought LI-COR’s reputation in gas analysis and environmental science but maintained Onset’s dual-platform architecture (HOBOlink for research, InTempConnect for pharma).

Onset HOBO’s recognized strengths include:

  • Research Community Standard — The HOBO brand carries exceptional recognition in academic and research communities worldwide. Cited in thousands of peer-reviewed publications, HOBO loggers are the default choice for field researchers, ecology studies, and building performance monitoring where brand familiarity and institutional knowledge simplify procurement
  • Affordable Entry Pricing — Starting around $60 for basic models and ranging to $250 for advanced Bluetooth MX-series units, HOBO loggers fit within grant-funded academic budgets. For organizations that need dozens of temporary monitoring points without capital expenditure approvals, Onset’s pricing is difficult to match
  • Bluetooth Simplicity — The MX-series allows smartphone-based deployment and data readout over Bluetooth without IT infrastructure, software installation, or network configuration. A researcher can unbox a logger, pair it to a phone, and start collecting data in minutes

Common Challenges with Onset HOBO

Organizations evaluating or currently using Onset HOBO frequently encounter these considerations:

  • Two platforms, two product lines, one company: Onset requires HOBOlink for HOBO research loggers and InTempConnect for InTemp pharma loggers. Organizations monitoring both research freezers and GMP storage areas must maintain two separate cloud platforms, two sets of credentials, two alert configurations, and two reporting workflows — from the same vendor
  • USB download dependency on most loggers: Outside the Bluetooth MX series, HOBO UX-series and U-series loggers require physical connection to a computer running HOBOware desktop software to retrieve data. This creates hours or days of data latency, gaps in monitoring continuity, and manual workflows that are difficult to defend in a regulated audit
  • InTemp is not full 21 CFR Part 11: While Onset markets the InTemp line as “designed for FDA compliance,” InTempConnect does not provide electronic signatures and offers only partial audit trail functionality. For facilities subject to FDA 21 CFR Part 11 requirements, the InTemp line falls short of what auditors expect for electronic records and signatures
  • ISO 17025 calibration as extra-cost service: Onset offers ANAB ISO/IEC 17025-accredited calibration services, but as an extra-cost offering rather than included in the base platform. For organizations managing both HOBO research loggers and InTemp pharma devices, calibration costs can accumulate separately
  • Dual alert systems across separate platforms: HOBO MX-series loggers provide Bluetooth-range notifications through the HOBOnet app, while InTemp devices use InTempConnect for alerting. Organizations managing both systems must configure alerts in two different interfaces with different capabilities and escalation workflows

How ATEK Addresses These Needs

Full 21 CFR Part 11 Native to One Platform: Onset’s InTempConnect provides FDA 21 CFR Part 11 compliance, but only for InTemp devices through a separate cloud platform. ATEK’s compliance capabilities are native to the core platform across all monitoring points. Electronic signatures, complete audit trails, ALCOA+ data integrity, and automated compliance reporting are built in for research and pharma monitoring through a single interface. For organizations managing both research environments and GxP areas, ATEK eliminates the need to split workflows across HOBOlink and InTempConnect.

One Platform Replacing Two: The operational burden of managing HOBOlink and InTempConnect as parallel systems — duplicate alert configurations, separate user accounts, two different reporting interfaces — disappears with ATEK’s unified cloud platform. Every monitoring point, whether in a research lab or a validated cold storage room, reports to a single dashboard with consistent alerting, reporting, and compliance documentation.

A2LA-Accredited Calibration Included: Onset offers ANAB ISO/IEC 17025-accredited calibration through their certified lab, but as a separate cost. ATEK’s in-house A2LA-accredited calibration lab provides accredited certificates included in base pricing with no separate billing. For Canadian facilities, the local lab eliminates the cross-border shipping that US-based calibration services require.

Continuous Monitoring Replacing Manual Downloads: Organizations using HOBO UX or U-series loggers know the routine: walk to each logger, connect via USB, launch HOBOware, download data, repeat. ATEK’s 30-second wireless data intervals replace this manual workflow with continuous cloud-synced monitoring. Six months of local data storage ensures zero data loss during network outages, and multi-channel alerting (phone calls, SMS, email) with escalation rules means excursions are detected in seconds, not discovered hours later during a manual download round.

Who Benefits Most from Switching

  • HOBOlink or InTempConnect customers tired of managing two platforms who want a single cloud-native system for both research and regulated monitoring environments rather than maintaining parallel Onset ecosystems
  • Facilities using HOBO UX/U-series USB loggers ready to eliminate manual download workflows and move to continuous real-time monitoring with automated alerting, especially those where data gaps from USB-dependent loggers have created audit findings or near-misses
  • Organizations that adopted InTemp for pharma but discovered its compliance limitations — missing electronic signatures, incomplete audit trails, and no IQ/OQ/PQ documentation — and need a platform that delivers full 21 CFR Part 11 compliance without workarounds

Making the Transition

Switching from Onset HOBO to ATEK accounts for the reality that many organizations have a mix of HOBO loggers, InTemp devices, and potentially both HOBOlink and InTempConnect subscriptions:

  1. Inventory and mapping — We catalog your current Onset deployment: HOBO logger models and locations, InTemp CX-series positions, HOBOlink configurations, InTempConnect alert rules, and any HOBOware desktop software installations still in use for USB-download loggers
  2. Parallel deployment — ATEK wireless sensors install alongside existing HOBO and InTemp hardware. Both systems run simultaneously during the validation period. For USB-dependent loggers being replaced, ATEK sensors begin capturing continuous data immediately, demonstrating the improvement from periodic manual downloads to 30-second intervals
  3. Compliance bridge — For InTemp positions that lacked full 21 CFR Part 11 compliance, ATEK’s validation team provides IQ/OQ/PQ documentation demonstrating that the new monitoring meets regulatory requirements the InTemp line could not fully satisfy. This documentation is included, not billed separately
  4. Platform consolidation — Once validated, HOBOlink subscriptions, InTempConnect subscriptions, and HOBOware licenses are retired. A single ATEK platform replaces what was previously two (or three) separate Onset systems, with 24/7 support during the first 30 days post-migration

When Onset HOBO May Be the Right Fit

Onset HOBO is the stronger choice for organizations whose primary need is affordable, accessible data logging for research and academic applications. University labs, ecological field studies, building energy audits, and grant-funded research projects benefit from HOBO’s low per-unit cost, Bluetooth simplicity, and decades of institutional familiarity. The HOBO brand’s recognition in peer-reviewed publications and the research community is genuine and well-earned. Organizations with no regulatory compliance requirements and no need for real-time continuous monitoring may find HOBO loggers deliver exactly what they need at a price point that is hard to beat.

When ATEK Is the Better Choice

Choose ATEK when you need:

  • Full FDA 21 CFR Part 11 compliance that InTemp’s partial implementation may not fully deliver — electronic signatures, complete audit trails, and ALCOA+ data integrity
  • A single unified platform replacing the HOBOlink/InTempConnect split, with consistent alerting and reporting across all monitoring points
  • Continuous 30-second monitoring replacing manual USB download workflows from HOBO UX and U-series loggers
  • A2LA-accredited calibration included in pricing, rather than Onset’s extra-cost NIST-traceable-only calibration service
  • Bilingual support from a Montreal-based team for Quebec and Canadian facilities, with Canadian data hosting and PIPEDA compliance

Frequently Asked Questions

Does ATEK provide the same research-grade logging as HOBO?

ATEK’s platform provides continuous environmental monitoring with 30-second data intervals, which exceeds what most HOBO loggers capture in terms of data density and real-time availability. For standard research applications — temperature, humidity, differential pressure — ATEK provides equivalent or superior data collection. However, HOBO offers specialized weather station products (RX3000, U30) and field-specific form factors that ATEK does not replicate. For pure field research with no compliance requirements, HOBO’s affordable pricing and Bluetooth simplicity remain well-suited.

Is ATEK FDA 21 CFR Part 11 compliant like Onset’s InTemp line?

Both ATEK and Onset’s InTempConnect provide native FDA 21 CFR Part 11 compliance including electronic signatures and complete audit trails. The key difference is that InTempConnect is a separate platform available only for InTemp devices, requiring organizations to manage HOBOlink for research loggers and InTempConnect for pharma devices as two distinct systems. ATEK provides unified 21 CFR Part 11 compliance through a single platform that covers all monitoring points without platform fragmentation.

How long does it take to migrate from HOBO loggers to ATEK?

Migration timeline depends on the complexity of your Onset deployment. Organizations with a few dozen HOBO MX or InTemp loggers typically complete the transition within 2-4 weeks including parallel operation and validation. Larger deployments with a mix of USB loggers, Bluetooth units, HOBOlink subscriptions, and InTempConnect accounts may take 4-8 weeks. The parallel operation period ensures continuous monitoring throughout the migration.

What happens to data stored in HOBOlink and InTempConnect?

Historical data in HOBOlink and InTempConnect can be exported before cancelling subscriptions. For USB-dependent loggers, data stored locally in HOBOware can be exported as CSV files. ATEK’s migration team assists with data retention planning to ensure compliance archive requirements are met. During parallel operation, both systems capture data simultaneously, maintaining continuous documentation through the transition.

Can ATEK replace both HOBO and InTemp with a single platform?

Yes. One of the primary reasons organizations switch from Onset to ATEK is to eliminate the dual-platform burden. ATEK’s single cloud platform handles both research-grade monitoring and GxP-compliant pharmaceutical monitoring from one dashboard, with one set of alert configurations, one reporting interface, and one user management system — replacing what required HOBOlink and InTempConnect as separate Onset systems.

Is ATEK more expensive than HOBO loggers?

HOBO loggers have a lower per-unit hardware cost ($60-$250) compared to ATEK’s all-inclusive per-monitoring-point pricing. However, the total cost comparison should include HOBOlink or InTempConnect subscription fees (~$70/year per logger), NIST-traceable calibration costs (billed separately), HOBOware Pro software licenses, validation documentation (not provided by Onset), and the operational labor of manual USB downloads for non-Bluetooth models. ATEK’s pricing bundles hardware, cloud platform, A2LA-accredited calibration, IQ/OQ/PQ documentation, training, and 24/7 support.
