The TR-71nw is a temperature recorder with two available sensor connections and can measure from -60 to 155°C.

The wide range of optional sensors offers increased measurement flexibility.

The functional buttons on the device allow you to make settings and start/stop recording. Use the Ethernet connection to automatically upload data to the cloud for any time, anywhere access, and receive alerts. Connect to a PC with a USB cable to download recorded data, create reports and make changes to settings.

It's perfect not only for the home and office but also for research labs, hospitals, and large institutions.

*1: Compatible wire sizes are as follows.

Single Wire : 0.32 to 0.65 (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 recom- mend 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 can- not be measured at temperatures below -20 °C.

*4: HTTP client. Proxy supported.

*5: When using external power, the internal temperature of the logger rises.

*6: 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.

*7: -10 to 45°C when using external power.
