TR-71nw Temperature Data Logger for Cloud Storage-Wired LAN
The TR-71nw is a temperature data logger that can monitor two temperature zones, while the TR-72nw is a temperature/humidity logger. 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.

*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-71wf and TR-71nw: 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.
- *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: When using external power, the internal temperature of the logger rises.
- *5: 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.
- *6: Approx. 10 days when Auto-upload Interval is 1 min, 1 yr when 1 hr, 1.5 yrs when 12 hrs or more.
- *7: -10 to 45°C when using external power. (for TR-7nw)
- *8: Software is not included in the package, but can be downloaded free of charge from the download page.
- *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.
