TR-71nw, TR-72nw, TR-72nw-S T&D Wired LAN Temperature and Humidity Data Logger Product ID: TR-71nw, TR-72nw, TR-72nw-S

The New Thermo Recorder: TR-7nw Series

T&D Corporation is proud to release the temperature and humidity data logger TR-71nw/72nw: a new LAN-based data logger for cloud storage. In addition to the existing wireless LAN model TR-71wf/72wf, we added the wired-LAN model with the same basic features to offer a choice of network connection methods. 

By using T&D WebStorage Service*1, a cloud service provided by T&D free of charge, it is possible to access stored data from your PC and mobile devices anytime from anywhere. Simply connect the data logger to the Internet with a LAN cable, and it automatically*2 starts uploading recorded data to T&D WebStorage Service, thus providing a remote access solution without the need for manual intervention.

*1: Internet access via LAN is required to access T&D WebStorage Service.

*2: In the LAN environment where DHCP can be used.

  • *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.
