Probe housing with high soil affinity, protection rating IP68.
The TP32MTT.03 is equipped with seven Pt100 sensors (Class 1/3DIN) and measures temperature at seven depths of +5cm, 0cm, -5cm, -10cm, -20cm, -50cm, and -1m, with respect to the ground (in compliance with WMO (World Meteorological Organization) requirements). The TP32MTT.03.1 has six built-in Pt100 sensors and measures temperature at six depths of +5cm, 0cm, -5cm, -10cm, -20cm, and -50cm, also with respect to the ground. The probe housing is made of fiberglass, ensuring complete impermeability and high thermal insulation in the vertical direction. The RS485 digital output using the Modbus-RTU protocol allows for the use of long connection cables. One side of the optional cable is stripped, and lengths of 5m or 10m can be selected. The power supply for the probe is DC 6-30V. ■ Subsurface temperature profiling with 7 or 6 depth measurements ■ WMO compliant, long-term high precision and stable measurement, RS485 Modbus-RTU output ■ High precision Pt100 sensors (JIS Class A), cable lengths of 5m/10m ■ Soil-compatible probe housing, protection rating IP68
