ULT & Liquid Nitrogen Monitoring
Protect irreplaceable biospecimens with continuous ultra-low temperature and cryogenic monitoring. Coverage from -80°C ULT freezers to -196°C liquid nitrogen storage.
Protect Your Most Valuable Samples
ATEK specializes in monitoring the extreme cold environments where your most irreplaceable samples are stored. From ULT freezers to liquid nitrogen dewars, our sensors provide continuous monitoring with immediate alerts.
A single ULT freezer failure can result in millions of dollars in lost samples and years of research. ATEK provides the early warning you need to protect your investment.

Cryogenic Applications
Monitoring for all ultra-cold storage equipment
-80°C ULT Freezers
Monitor ultra-low temperature freezers storing biospecimens, cell lines, and research materials.
LN2 Storage
Detect when liquid nitrogen falls below the chosen probe position, with separate temperature monitoring for cryogenic storage.
Cryogenic Dewars
Monitor temperature and binary LN2 low-level status in dewars storing embryos, stem cells, and tissues.
-150°C Freezers
Monitor mechanical cryogenic freezers used for long-term sample preservation.
Choose an LN2 Refill Warning Point
The ATEK WiFi LN2 level monitor detects whether its probe tip is submerged or exposed. Position the probe up to 4 feet deep using the adjustable stainless steel rod, according to your tank and refill procedure. The monitor reports a binary low-level state; it does not measure nitrogen volume or continuous liquid depth.
A low-level notification prompts staff to check and refill the tank. Pair it with a separate suitable temperature sensor, and define the alert recipients and response procedure for your facility.
Temperature Capabilities
Sensors for the entire cryogenic range
| Temperature | Application | Accuracy |
|---|---|---|
| -80°C to -86°C | ULT Freezers | ±0.5°C |
| -150°C | Mechanical Cryo | ±1°C |
| Depends on tank and probe position | LN2 Vapor Phase | Confirm selected temperature sensor |
| Near -196°C | LN2 Liquid Phase | Confirm selected temperature sensor |
Frequently Asked Questions
How does ATEK monitor -80°C ULT freezers?
ATEK uses specialized ultra-low temperature sensors with thermocouples rated for -86°C. These sensors provide continuous monitoring with ±0.5°C accuracy and immediate alerts for any temperature deviation.
Can ATEK monitor liquid nitrogen levels?
Yes. The ATEK WiFi LN2 level monitor reports whether the probe tip is submerged (0) or exposed (1) at the chosen refill point. Its position is adjustable up to 4 feet. It detects a low-level threshold rather than measuring nitrogen volume or continuous liquid depth. Temperature monitoring requires a separate suitable sensor.
What happens if a ULT freezer fails overnight?
ATEK provides 24/7 monitoring with multi-channel alerts (SMS, email, phone calls). Critical temperature excursions trigger immediate escalation to ensure someone responds, even at 3 AM.
Does ATEK support biorepository accreditation?
Yes, ATEK provides the continuous temperature documentation, audit trails, and compliance reports required for CAP, AABB, and ISBER accreditation standards for biorepositories.
