ML3 ThetaProbe Soil Moisture and Temperature Sensor

The next generation of ThetaProbe

The new ThetaProbe has extra features, improved performance and a new look. With its 1% accuracy the ThetaProbe continues to set the standard for soil moisture measurement but now also measures soil temperature.

  • New built-in temperature measurement: - ± 0.5°C accuracy
  • New adaptable cable system: - extendable, easy handling
  • New white body: - reduces radiative heating
  • Improved performance in saline soils: - usable in soils up to 2000 mS.m-1

Moisture Meter type HH2

Simple, versatile operation - The ThetaKit includes the HH2 Moisture Meter which offers impressive functionality in a compact, handheld unit, designed for field use. Readings are displayed on the LCD and can be stored to memory for later download to a PC. Up to 2100 time-stamped readings can be stored. The unit can be operated with one hand, for convenience in the field.

USB to RS232 adapter cable

Please Note: unless your PC has an RS232 port (most do not) and if you want to down load readings to it's hard drive then your ThetaKit will need a USB to RS232 adapter cable. These can be obtained at low cost from many IT suppliers, but for stable performance we recommend the high-spec USB-RS232 model (sold below).
