Thermocouple -30 ... +70 °C | STP01

soilfor soil thermal profile measurement

The STP01 model is manufactured by Hukseflux, and is a sensor that is appropriate for a very precise measurement of temperature versus profundity in the dirt. There is a great precision gradient measurement by accurate placing of the tc joints (+/- 1mm). There is a measurement of tc voltage that is relative to the junction at 50 cm, which has a great precision and stability of the relative distance between sensors to logger cabling. It comes with an easy quality assurance and servicing, which self-test is possible by heating and looking at the pulse response. The unit can hold 5 thermocouples and one reference Pt100 temperature sensor, which the key thing in the configuration is the focal copper-nickel (CuNi) wire.
