Access Temperature and Humidity Data Measured with a High Precision Sensor Anytime from Anywhere

High precision IoT temperature and humidity logger connectible via wireless LAN, Bluetooth and USB!

The TR72A2-S can measure temperature from -25 to 70°C and humidity from 0 to 99%RH at high precision. The LCD screen allows the simultaneous display of either the current values of two channels, the highest and lowest values of channel 1, or the highest and lowest values of channel 2. The ALM icon on the LCD alerts the user of the occurrence of an alarm.

Use the wireless LAN feature (compatible with the enterprise communication) to auto-upload data to the cloud for anytime anywhere access and receive warning notifications. By using Bluetooth or USB, you can configure device settings, generate reports, download data, and view the uploaded data. You can download the recorded data and change the device settings on a PC via USB Connection. A USB cable (option US-15C) is required to connect the device to a PC.

Features

The TR72A2-S uses a wireless LAN access point to auto-upload recorded data and warning notifications to the free-of-charge cloud-based “T&D WebStorage Service”. You can download data and configure device settings using the dedicated app "TR7 for Windows (for Windows)" or "T&D Thermo (for smartphone / tablet)". By using the Windows software “T&D Graph”, you can easily view and analyze data from a PC.

  3. When continually used in environments with temperatures above 60 °C, accuracy of humidity measurements will decrease over time. Also, humidity cannot be measured at temperatures below -20 °C.
  4. -
  5. When using EAP-PEAP, server certificate verification using the CA certificate is not available.
  6. Client function. Only HTTP proxy is supported (not HTTPS).
  7. The optional AC adaptor “AD-05A2” (Type A Plug) can be used in the USA and Canada, and “AD-05C2” (Type C Plug) in Europe. For usage in other countries, please contact your local distributor.
  8. Battery life in the table above is for two AA Alkaline type batteries, and varies depending upon multiple factors including frequency of communication, network environment, ambient temperature, recording interval, and battery performance. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life.
  9. Free software download and information on OS compatibility is available on the Software page of our website at https://tandd.com/software/.
  10. TR7 for Windows requires a PC with Bluetooth capability (4.0 or above) or a USB communication cable (available as option: US-15C). The specifications listed above are subject to change without notice.
