SM150 Kit
- Complete kit for coco, soil, and substrate moisture measurement
- ± 3% accuracy
- Easy to use and highly portable
The SM150 Kit is an affordable tool for obtaining reliable moisture measurements with minimal soil disturbance. The cable and connector are watertight – an essential requirement for potentially wet environments.
The kit comprises an SM150T Coco & Soil Moisture Sensor, a dedicated HH150 Moisture Meter, and a carry case. The kit comes with substrate calibrations for perlite, coir, peat, and mineral wool, as well as soils.
The HH150 handheld meter is lightweight and is very easy to use, being a readout-only device (no data recording or PC complications). To make a measurement, just insert the SM150T into the substrate and press the Read button.
Note: The HH150 Moisture Meter does not provide temperature indication from the SM150T Sensor
The new SM150T measures soil moisture and temperature with research-grade accuracy. It offers stable, robust and reliable performance at a great price.
The new SM150T’s advanced patented electronics and tough build produce a highly dependable 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.
The SM150T is a dual purpose probe – it can be used portably for instant moisture readings, or left installed in the soil connected to a data logger, to provide long-term moisture and temperature data.
