WET150 Kit is a portable and rugged solution for researchers who need to assess moisture and salinity conditions in soils and substrates.
The Kit makes fast soil/substrate measurements of three crucial variables that influence plant growth: moisture content, temperature*, and electrical conductivity (EC) – a strong indicator of the general nutrient level.
The WET150 Meter is a lightweight and easy to use readout-only device (no data recording or other complications). Operation of the kit is straightforward – the user inserts the WET150 into the soil or substrate and presses the “Read” button on the meter to take and display the measurement.
The WET150 Sensor comes complete with calibrations for mineral and organic soils plus perlite, coir, peat, and mineral wool substrates soils.
