ST-21P Soil Temperature sensor

Overview

The ST-21P sensor measures absolute temperature of the soil once it is buried in. The sensor's body has low thermal conductivity that provides accurate measurements in shallow substrate like a Rockwool slab, for instance.

The probe is connected by a standard 1-meter cable to the waterproof box with the signal conditioner inside.

Standard output cable length between signal conditioner and monitor is 4 meters.

Every sensor is tuned and calibrated within the measurement range. The tolerance range is ±0.08 ℃ only.
