STP01 accurately measures the temperature profile of the soil at 5 depths close to its surface. It is used for scientific grade surface energy balance measurements. The sensor is buried and usually cannot be taken to the laboratory for calibration. The on-line self-test using the incorporated heating wire offers a solution to verify STP01’s measurement stability.
- temperature at 5 depths from 0 to 0.5 m
- -30 to +70 °C
