TR-72nw Temperature and Humidity Data Logger

The TandD TR-72nw is a temperature and RH data logger, but is available in a high precision model--TR-72nw-H.  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) Sensor Description Thermistor Polymer Resistance Measurement Channels Temperature 1ch Humidity 1ch Measurement Units °C, °F %RH Measurement Range Internal Sensor - - External Sensor 0 to 55°C 10 to 95%RH Accuracy ±0.5°C ±5%RH at 25°C, 50%RH Measurement Resolution 0.1°C 1%RH Responsiveness Response Time (90%): Approx. 7 min.

Display Languages *8 English *1: 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. *2: HTTP client. Proxy supported (for firmware version 1.05 or above for TR-7wf). *3: 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. *4: Approx. 10 days when Auto-upload Interval is 1 min, 1 yr when 1 hr, 1.5 yrs when 12 hrs or more. *5: -10 to 45°C when using external power. (for TR-7nw) *6: Software is not included in the package, but can be downloaded free of charge from the download page. *7: For installation, it is necessary to have Administrator (Computer Administrator) rights. *8: We recommend using an operating system in the same language as the display language. Operation in different languages is not guaranteed.
