What the catalog describes
The ATEK Wi-Fi Differential Pressure Transmitter is listed for cleanrooms, isolation rooms, and containment areas. Its model reference is ATEK-T-WF-DIFFPRES. The supplied catalog description says it streams room-pressure readings to the ATEK platform and identifies a CMOS differential pressure sensor. Those are the documented purpose and sensing description for this device. They do not answer every question about a proposed room or measurement arrangement.
For teams in the United States and Canada comparing devices, the useful starting point is the ATEK product page. Separate the catalog’s measurement specifications, network description, power information, and included items before comparing the transmitter with your requirements. This guide follows those fields without adding a mounting procedure or a claim about suitability at a particular site.
Keep the measurement specifications separate
The catalog lists a differential pressure range of −500 to +500 Pa. It separately lists 0.10 Pa accuracy and 0.01 Pa resolution. Long-term stability appears as ±0.05 Pa/year. Keep the labels and units attached to the values when recording them in a device comparison. The stability figure should retain its annual unit; it should not be copied into the accuracy field. Likewise, the listed resolution should not replace the listed accuracy.
Decision rule: Match each required measurement field to the corresponding catalog field. If your specification calls for accuracy, compare it with the accuracy entry. If you need clarification about the stated range, resolution, or stability, ask ATEK about that entry rather than treating another value as its substitute.
The short description does not provide the conditions behind every measurement figure. Useful questions include which operating conditions apply to the stated accuracy and what additional details the available datasheet provides. Obtain those details before drawing conclusions about a specific measurement arrangement.
Review the network and power entries
The documented connectivity is Wi-Fi 2.4 GHz with WPA2-Enterprise and real-time connectivity. Record both the frequency and the named connectivity option. Ask ATEK which network configuration is supported for your intended setup and which information is needed to configure the device. Listing WPA2-Enterprise does not supply a complete onboarding procedure.
The power entry is 5 V / 500 mA DC. The catalog also lists an internal rechargeable battery backup. Keep the external power specification distinct from the battery description. Neither the word rechargeable nor the presence of a backup supplies a battery runtime figure. If runtime is relevant to your purchasing decision, request the documented figure and its conditions. Do not assign a runtime from the external supply specification.
Compare the enclosure, display, and included records
The listed enclosure dimensions are 84 × 84 × 32 mm. Use those dimensions in your comparison and ask which drawings or other dimensional details are available if the external size alone is insufficient. This guide does not infer mounting orientation, fittings, tubing dimensions, or mounting hardware from the enclosure measurements.
A backlit display, min/max reset, and power-loss detection are listed features. Ask how those features are presented and operated if they are part of your device selection criteria. The catalog also says the transmitter ships with a calibration certificate and a unique serial number. Request an explanation of the supplied certificate’s scope and how the serial number appears in the accompanying records.
Clarify the storage entry before relying on it
The catalog lists 6 months of on-board storage. Preserve that wording in the comparison. The storage duration alone does not describe what happens during a network interruption, whether readings are replayed, or how storage is retrieved. Those are separate questions to ask ATEK when they matter to the proposed use.
Keep a purchase discussion tied to these documented fields and the remaining questions that affect your requirements. The device page is the source for the product details used here. Browse the ATEK shop to compare the other offered devices, then confirm the current product information with ATEK before choosing a unit.
