Our easy-to-use USB computer connection makes things not only simple, but allows you to connect several units at the same time.
Simultaneous Monitoring of Multiple Channels of Data
With the attached software it is possible to view current measurements and current trends in a changing graph form. Graphs can be opened for the same number of units as are connected and can be simultaneously viewed.
Large Data Capacity: 8,000 Readings x2 Channels (TR-73U:8,000 x3 Channels)
Each unit is equipped with a large data capacity of 8000 readings x 2 channels for TR-71U/72U and 8000 readings x 3 channels for TR-73U.
Accurate, Compact, Lightweight and Affordable
Our exclusive design and technology has allowed us to create a highly accurate yet compact and lightweight unit (55x88x24mm 95g) that is unbelievably affordable.
One Year Continual Use on One Set of Battery
Using our specially designed low energy consumption circuit this unit can run on two AA alkaline battery for up to one year of continued use. No need to worry about where you place it as the battery will allow you to measure and record over long periods of time whether the unit is in transit or in a distant place.
Battery life will depend on the recording environment, recording interval, communication frequency, and ambient temperature. The above battery life test was carried out using brand new batteries and in no way do we guarantee a battery's life.
Adjustment Function
By setting adjustment values beforehand, you can record and display the post-adjusted measurement values.
High Speed Data Transfer
Possible to transmit one unit of full data (8,000 readings) to computer in about 8 seconds.

- *1: When used in environments where temperature and humidity are over the values of 50°C 75%, 60°C 50%, 70°C 35%, and 80°C 25%, sensor hysteresis may fluctuate by values greater than ±1.5%RH. Under certain circumstances, it may take some time to return to normal measurement capability.
- *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.
