TR-50 Comm Cradle
RTR-57U Data Collector
Looking for a data logger to use in harsh environments? Look no further. Our new T&D loggers are IP67/IP64 rated for water resistance. They also include a display so you don’t have to download the data to see what the current temperature is.

Choose the model TR-52 and attach an external probe to extend the temperature range. With a 16,000 reading memory bank, you can record up to 666 days at an interval of one hour. You can program these loggers to record at virtually any interval from 1 minute to 1 hour for the TR-51A, and from 1 second to 1 hour for the TR-52.

Add the optical communication cradle to download directly to your PC, or for remote downloading add on the TR-57U Handheld Collector unit. With the TR-57U handheld unit your loggers stay in place while you download without cables or connectors right to the handheld for a later dump to the PC.

You won’t find a more rugged datalogger than our TR series.

Lithium Battery (CR-2) can be used for this unit, however the possible temperaure measurement will be - 20 to 60°C. If you are measuring below -20°C or above 60°C, we recommend the Optional Battery Set TR-00P2
Battery Life differs depending on measurement environment and battery performance.
Not for continued immersion.
The water resistance rating with the sensor or input cable connected is IP64.
