0000097-t-d

The TR-72nw temperature and humidity data logger is a two channel model with an external thermistor sensor and a measuring range of 0 to 55°C and a humidity range of 10 to 95% RH. In addition to the standard features such as battery operation and USB communication (through optional cable, sold separately), the TR-72nw supports communication with mobile devices. By using T&D’s WebStorage Service, users can access stored data anytime from the cloud.

  • *1:For TR-71wf: When wireless LAN communication is used frequently, the measurement of the internal sensor may rise by around 0.3°C.
    For TR-71nw: When using PoE or USB as the power supply, the data logger itself generates heat and internal sensor will report a temperature approximately 15°C higher than ambient.
  • *2: 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.
  • *3: HTTP client. Proxy supported (for firmware version 1.05 or above for TR-7wf).
  • *4: 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.
  • *5: Approx. 10 days when Auto-upload Interval is 1 min, 1 yr when 1 hr, 1.5 yrs when 12 hrs or more.
  • *6: -10 to 45°C when using external power (PoE or USB). (for TR-7nw)
  • *7: Software is not included in the package, but can be downloaded free of charge from the download page.
  • *8: For installation, it is necessary to have Administrator (Computer Administrator) rights.
  • *9: If you are using Windows 8, please note that our software is designed to be used in “Desktop” mode only.
  • *10: We recommend using an operating system in the same language as the display language. Operation in different languages is not guaranteed.
