Logtag TREL-8 Dry Ice External Probe Logger

TREL-with-external-plug-small

If the life of the logger is critical when monitoring ultra low-temperature environments, TREL8 loggers with an external sensor are an economical alternative. It will last for 2 years assuming a 15 minute logging interval and once a month download. A red alert LED indicator provides a visual indication when there is a temperature excursion. A special feature in the logger, if activated, stores temperature data even if the logger start button has not been pressed. Using LogTag download interface and LogTag Analyser software, the recorder can be easily configured for recording temperatures and can also be used to download recorded data. The software also allows for analysis of downloaded data by viewing it as a graph or a table.
