The TR7U series features USB type data loggers that enable 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 TR7U series 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.
