STP-2 Soil Temperature Probe
An optional soil temperature sensor can be used with the EGM-5 for measurement of soil temperature. It
is commonly used with the SRC-2 Soil Respiration Chamber and CPY-5 Canopy Assimilation Chamber.
It is a rugged sensor with electronics housed in an anodized aluminum
enclosure with stainless steel tip.

Soil Moisture and Soil Temperature Sensor
An optional soil moisture and soil temperature sensor (HydraProbe II - Stevens Water Monitoring
Systems) is available for use with the EGM-5. It is an all-in-one, in-situ sensor that can measure both soil
moisture and soil temperature.

For best results the 3 prongs should be pushed all the way into the ground until the white body of the
sensor is flush with the soil surface.
Recalibration of this sensor is not necessary.
