Thermistors provide accurate and reliable long-term temperature measurements and are used widely in Geothermal Energy recovery systems to monitor temperature profiles with vertical heat exchangers.

They comprise of a series of sensors mounted along a multi-core cable to customer requirements in terms of the number and spacing of each sensor.
