The soil thermometer is used  for the measurement of soil temperatures in different measuring depths in connection with UNIKLIMA. The inserting thermometer was developed particularly for still unaffected, grown soils and is available in two different lengths.

All sensors are adjusted again  in our climatic cabinet despite manufacturer calibration.  The free exchangeability of the sensors without local alignment with accuracies achieved in the climatic cabinet is given by the software calibration.
