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-52S 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 second to 1 hour.

Now the TR series features a 4 year battery life and LED alarm indicator. From the front panel you’ll now be able to visually check if alarm conditions have been met during the log cycle. With a high speed USB connection downloading all 16,000 readings only takes 20 seconds.

Add the USB 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.

*1 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-10P2 *2 Battery Life differs depending on measurement environment, battery performance, and log interval (see data sheet). *3 Not for continued immersion. *4 The water resistance rating with the sensor or input cable connected is IP64.
