ST01 Soil Temperature Sensor for Extreme Conditions

ST01 is a high quality temperature sensor that is specifically designed for soil temperature measurement in extreme environments. Using top quality materials it is suitable for hostile conditions as encountered in outdoor installation (temperature, radiation, chemicals). It is designed to have a record-breaking lifetime with optimal stability. Employing a platinum sensor, at extreme temperatures a higher accuracy can be attained than with commonly used thermistors.

An ultra-stable sensor that can withstand extreme conditions

The measurement of soil temperature is recommended by the World Meteorological Organisation at depths of 5, 10, 20, 50 and 100 cm. Proper installation of soil temperature sensors requires a lot of effort. Once installed, sensors are usually left alone without calibration for a long time. This means that the sensor and cabling should be very reliable and stable over time. ST01 is designed to be an ultra-stable sensor that can withstand the extreme conditions met in meteorological use; partially sub-soil, partially above-soil installation.

Suggested uses for the ST01 Soil Temperature Sensor include extreme environments: arctic & desert regions, polluted soil
