Th2 Soil Temperature Probe

The durable, water proof temperature probe for soils, fluids, gases.
The thin body and sharpened tip reduce the soil disturbance when installed and ensures a good thermal contact to the soil. A heat conducting filling inside improves the thermal conductivity from the casing to the probe - for a fast response punctual temperature pick-up and minimised cable temperature influence.

Advantages

Highest accuracy
Minimised soil disturbance
Punctual temperature pick-up
Maintenance-free and
durable
Cable strain-relieved
Three temperature probe
types available
