The TR-72nw is a temperature/humidity logger, but is available in a high precision model--TR-72nw-S.  By using T&D WebStorage Service, a cloud service provided by T&D free of charge, it is possible to access stored data anytime from anywhere.

Power Over Ethernet:  PoE IEEE 802.3af (TR-72nw or TR-72nw-H only).

Mobile App

Android OS, iOS
(For the compatible versions, please go to the app download page from here.)
Display Languages *9 English
  • *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.
