Delta-T Devices affordable research-grade SM150 sensor has been upgraded to include substrate calibrations for perlite, coir, peat, and mineral wool, as well as soils. The sensor is designed to provide rapid and accurate measurements of substrate moisture content – and is particularly easy to insert without damaging roots or disturbing the growing medium.
The SM150 is available as part of a complete kit along with a dedicated HH150 moisture meter and carry case. The HH150 hand-held meter is lightweight and easy to use, being a readout-only device (no data recording or PC complications).
With the SM150 kit, growers can easily check the consistency of growing conditions—saving time and money. The moisture status of thousands of plants can be monitored daily. The sensor is tough enough to be used all day every day in busy growing environments.
The SM150 achieves ± 3.0% accuracy when measuring water content and its performance is stable across wide ranges of temperature and salinity. Its construction uses an industrial grade connector and high specification materials throughout.
The SM150 can also be used as a stand-alone, logable sensor and can be buried long-term if desired. It can be used with the Delta-T GP1 Data Logger for precision irrigation control. Readings can be used to optimise irrigation scheduling, or the SM150 can be added to an automatic irrigation system. The sensor’s compact size allows it to be installed in plant pots or grow bags The SM150 provides a simple, rugged solution to checking the uniformity of growing conditions across multiple types of growing media.
