Overview

The Senseca TP32MTT.03.A is a single soil temperature probe designed to measure soil temperature at a depth of 5 cm using a 4-wire Pt100 sensor (1/3 DIN class). It is suitable for agricultural, environmental and microclimate monitoring applications requiring reliable near-surface soil temperature measurements.

The probe features a solar radiation screen made from UV-resistant ASA technopolymer with low thermal conductivity and high reflectivity, designed to minimise the influence of solar radiation on temperature measurements. It has a working temperature range of -40…+85 °C and an IP67 protection rating. For installation, the probe is secured using a metal spike inserted into the ground, while the connection cable must remain above soil level. It is available with a 2, 5 or 10 m 4-pole cable terminated with open wires.
