For the Wireless Leaf & Soil Moisture/Temperature Station (# 6345)
The probe is designed to measure soil temperature in order to provide temperature compensation for the Watermark Soil Moisture Sensor.
The sensor is a precision thermistor which produces a resistance change proportional to temperature. It is epoxyencapsulated in a 316 alloy stainless steel body with vinyl strain relief. The 22 AWG direct burial cable is resistant to damage from pests, moisture or UV.
To ensure accurate readings when measuring outdoor air temperature, the Multi-Purpose Temperature Probe should be shielded from direct sunlight and other sources of reflected or radiated heat. We recommend the use of the Radiation Shield (#7714) for this purpose.
