The TR-72Ui measures and records one channel of temperature and one channel of humidity.

The TR-71Ui & 72Ui are USB type data loggers that enables the downloading of recorded data by connecting directly to a PC. Also, the newly added infrared communication function can now be used to collect recorded data from the TR-71Ui/72Ui without a PC.
By using a Data Collector TR-57DCi with infrared function, the collected data can be easily displayed in graph form without physically gathering the loggers, enabling the immediate on-the-spot checking of continually-changing data.

(*1): There are two types of temperature sensor for TR-71Ui depending on measurement range.
(*2): One data set consists of readings for all channels in that type of unit.
(*3): Battery life depends upon the measuring environment, recording interval, and quality of the battery being used. When infrared communication function is enabled, battery life may be shortened if the unit is used under the inverter type fluorescent lighting.
