The TR-72wb-S WiFi & Bluetooth Temperature Humidity Data Logger is a high precision two-channel model with an external sensor and a measuring range of -25 to 70°C and a humidity range of 0 to 99%RH. In addition to the standard features such as battery operation and USB communication (through optional cable, sold separately), the the TR-72wb-S supports wireless communication using either WiFi for connection a network or Bluetooth for connection to the mobile devices. By using T&D’s WebStorage Service, users can access stored data anytime from the cloud.

Access to Recorded Data

By using a wireless LAN, data is automatically uploaded to the WebStorage Service (registration required). The service can be used with mobile devices such as smartphones and tablets allowing users to monitor current readings, alerts and downloading of data. The ThermoWeb application must be downloaded and installed on any mobile device. Data can also be downloaded to a PC with a USB communication cable (sold separately).

The TR-72wb-S is a high precision temperature/humidity logger and it can be purchased in a standard precision version, the TR-72wb.  The TR-71wb is a temperature data logger that can monitor two temperature zones, while In addition to the basic features of T&D's standard data loggers such as battery operation and USB communication function*1, the TR-71wb/72wb supports communication with mobile devices and can be used without a PC. By using T&D WebStorage Service*1, a cloud service provided by T&D free of charge, it is possible to access stored data anytime from anywhere.

*1: To carry out the auto uploading of recorded data to T&D WebStorage Service, it is necessary to have Internet access via a wireless LAN and a T&D WebStorage Service User ID.

  • *1: Compatible wire sizes are as follows. Single Wire : 0.32 to Ø0.65 ( AWG 28 - 22 ), Twisted Wire : 0.08 to 0.32 ( AWG 28 - 22 ), 0.12 or more in diameter, Stripping Length : 9 to 10
  • *2: When Auto Upload is used frequently, the measurement of the internal sensor may rise by around 0.3°C . When using external power, the data logger itself generates heat and the internal sensor will report a temperature much higher than ambient; we recommend using an external temperature sensor in this case.
  • *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: The WPS feature is not available when WEP ( 64bit/128bit ) or WPA-PSK ( TKIP ) is selected in Access Point Settings. If you wish to use the WPS feature, please select WPA2-PSK ( AES ) or disable wireless security.
  • *5: HTTP client. Proxy supported. ( for firmware version 1.05 or above for TR-71wf/72wf).
  • *6: When using external power, the internal temperature of the logger rises.
  • *7: Battery life varies depending upon multiple factors including frequency of communication, LAN 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.
  • *8: -10 to 45 °C when using external power ( TR-7nw only ).
  • *9: For installation, it is necessary to have Administrator ( Computer Administrator ) rights.
  • *10: We recommend using an operating system in the same language as the display language. Operation in different languages is not guaranteed. The specifications listed above are subject to change without notice.
