The SM150 Soil Moisture Kit provides an affordable and easy-to-use tool for obtaining reliable moisture measurements with minimal soil or substrate disturbance.
Introduction
The kit comprises an SM150T* Soil Moisture Sensor, a dedicated readout meter and a carry case. The cable and connector are watertight – an essential requirement for potentially wet environments.
The meter displays volumetric water content (% volume). Please note that although the SM150T Sensor has a built-in temperature sensor, the meter does not measure or display temperature.
Simple operation
The 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 mineral, peat mix, coir, mineral wool and perlite (plus also provides raw voltage output) – 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.
Other Delta-T soil moisture kits
Two alternative Delta-T Devices moisture measurement kits are available if greater accuracy or electrical conductivity (EC) measurements are required.
*The SM150 Kit was previously supplied with the SM150 Sensor, but now comes with the SM150T Sensor.
