DRM4 - Digital Resistance Multimeter 4 DigitsThe DRM4 meter is used with the TSSB16 Thermistor String Switchbox and TSX Thermistor String to test resistance readings on thermistor points. This allows field users to check string points quickly without a laptop and Prolog Data Logger software.
TSSB16 - Thermistor String Switch BoxThe TSSB16 switchbox is a testing module for TSX Thermistor Strings. In combination with the DRM4 Resistance Meter it can verify quickly that each channel of the Thermistor String is working correctly.
TSX - Thermistor StringThe TSX Thermistor String is primarily used for ground temperature monitoring. Once this unit is installed the ground, it can provide up to 16 points of data at different depths.
