Soil Temperature Probe

Clear selection

The TP32MTT.03 Soil Temperature Probe is equipped with seven Pt100 1/3 DIN sensors for the measurement of temperature at +5 cm, 0 cm (ground level), -5 cm, -10 cm, -20 cm, -50 cm and -100 cm.

The sensors are housed within a fibreglass tube that is easy to bury and ensures perfect impermeability and high thermal insolation along the vertical axis.

The TP32MTT.03 can be used with HD 32MT.1 and HD 32MT.3 data loggers or any other compatible RS485 MODBUST-RTU system.

Note: CPM12-8D 8-pole cable must be ordered separately (2 metres, 5 metres or 10 metres).

  • CP24 PC connecting cable for configuration of the MODBUS parameters. With built-in RS485/USB convertor. 8-pole M12 connector on the probe side and USB A-type connector on the PC side.
  • TP32MTT.03A Accessory to create the hole in the soil to insert the probe.
  • TP32MTT.03B Accessory to signal the presence of the probe.
