The SM150 Kit provides growers with an extremely affordable and easy to use tool for obtaining reliable moisture measurements. The SM150 Soil Moisture Sensor has been designed for repeated insertion into soils and substrates, the sharp pins causing minimal disturbance. The cable is fitted with a robust IP68 connector and is watertight - an essential requirement for potentially wet environments. 

Substrate calibrations

The SM150 Kit includes substrate calibrations for perlite, coir, peat, and mineral wool, as well as soils - providing a simple, rugged solution to checking the uniformity of growing conditions across many types of growing media.
