T&D TR-43A Thermo-Hygrometer Data Logger with External Probe for Storage and Facility Monitoring
- Channels : Temperature 1ch, Humidity 1ch
- Range : Temperature: 0 to 55°C / Humidity: 10 to 95%RH
- Comm Interfaces : Bluetooth 4.2 (Bluetooth Low Energy)
2-Channel Temperature and Humidity Data Logger with Mobile App Connectivity
Ideal for monitoring transport, storage, restricted-access areas, homes, and offices
Accurate and convenient monitoring: This logger transmits temperature and humidity data to your mobile device via Bluetooth Low Energy. From the app, data can be uploaded to our complimentary cloud service, "T&D WebStorage Service," using WiFi or a mobile network.
Reliable measurement range
The TR43A sensor measures temperature from 0 to 55°C and humidity from 10 to 95％RH. The device body is rated IP64*, making it suitable for environments from -40 to 80°C.
Compact and versatile design
Its all-in-one design allows easy deployment in various settings, from industrial storage to residential or office monitoring. Users value its simplicity, real-time data access, and the ability to manage logs remotely.
*2: Battery life depends on factors like ambient temperature, recording interval, app usage, and battery condition. Estimates are based on a new battery and do not guarantee actual performance.
*3: Estimated battery life assumes data recording at intervals longer than 10 seconds with daily graph display in the app.
*4: The IP64 rating applies to the logger with the sensor attached. The temperature-humidity sensor itself is not water resistant. Specifications may change without notice.
