Digit-TLH

The Digit-TLH logs temperature, approximate light, and relative humidity.


Battery powered data logger


The Digit series collects data in a remote location, and stores it to internal memory. When finished, the data can be downloaded via the convenient USB connector. Traditional applications include shipping, weather monitoring, agriculture, and refrigeration. The miniature size makes it convenient for logging temperature on-the-go.


Every data point is given a timestamp, so it is possible to see when temperature changes occur, and with 7 different log intervals, it is easy to customize how frequently data points are collected. Use the 2 programmable LED alarm thresholds to detect if temperatures exceeded permissible boundaries, such as in a refrigerator. One unique feature to this data logger is the included approximate ambient light sensor.
