There are three types of soil temperature sensor thermometer: Sheathed Pattern, Insulated Pattern & Angle Pattern. All soil temperature sensors have depth ranges for taking temperature measurements both on & below the surface of the earth.
This soil temperature thermometers are used for depths up to 3 metres and consists of a solid stem thermometer fitted into a transparent glass sheath. Each depth is established by inserting a steel tube into the ground and lowering the thermometer by chain down into the tube. The thermometer bulb is embedded in paraffin wax to give a slow response time enabling it to be withdrawn to take readings.
