The Vaisala Soil/Water Temperature Probe QMT103 / QMT110 is particularly well suited for the precision measurement of ground and soil temperatures. All the materials used in its manufacture have been carefully selected to withstand various types of environmental stress and a wide range of temperatures.

The measurement accuracy and stability of the temperature probe are based on a Pt-100 type sensor element, which is specied to a level of precision of 1/4 DIN 43760B. The probe includes a 5-meter cable with a black, weather-resistant polyurethane (PUR) sheath which withstands both abrasive wear and extreme temperatures. A 5-pin watertight connector is molded to the other end of the cable for quick installation and replacement.

The Vaisala Soil/Water Temperature Probe QMT110 model has a 10-m cable with connector.
