SM150T Kit


The SM150 Soil Moisture Kit provides an affordable and easy-to-use tool for obtaining reliable moisture measurements with minimal soil or substrate disturbance.

SKU: SM150T-K Category: Product ID: 5743


The kit comprises an SM150T Soil Moisture Sensor, a dedicated HH150 Moisture Meter and a carry case. The cable and connector are watertight – an essential requirement for potentially wet environments. The HH150 Meter displays volumetric water content (% volume). Please note that although the SM150T Sensor has a built-in temperature sensor, the HH150 Moisture Meter does not measure or display temperature.

Simple operation
The HH150 hand moisture meter is lightweight and is very easy to use, being a readout-only device (no data recording or PC complications). Operation is simple – just insert the SM150T into the soil or substrate and press the Read button to make a reading.

Horticulture applications
The SM150 Kit comes with substrate calibrations for perlite, coir, peat, and mineral wool, as well as soils – providing a rapid, rugged solution for checking the uniformity of growing conditions for many types of growing media.
The SM150T is easy to insert and install – its sharp pins minimise soil disturbance and preserve the original soil structure around the measurement rods.

SM150T Sensor:

Research grade soil moisture sensor
The SM150T’s advanced patented electronics and tough build produce a highly reliable soil moisture sensor with exceptional salinity and temperature stability. The SM150T is engineered to withstand long term burial – the sensor, connectors and cable are all environmentally protected to IP68. It offers moisture accuracy of ± 3% (after soil specific calibration) and the built-in temperature sensor achieves ± 0.5°C.
