The WET150 is a digital SDI-12 multi-parameter soil sensor from Delta-T Devices. The WET150 is easily integrated into SDI-12 networks and simultaneously measures soil and substrate moisture, temperature, and EC (electrical conductivity). The WET150 is ideally suited to both commercial horticulture and scientific research. Up to 62 WET150s can be connected to just one SDI-12 control device (such as a SDI-12 enabled data logger). The WET150 is also available in portable kit form alongside the WET150 Meter instant readout unit.
