With the ML3 ThetaProbe Soil Moisture Sensor it’s easy to make reliable, accurate soil moisture measurements. Simply insert the soil moisture probe into the soil, connect to your data logger or readout unit, provide 5-14 VDC at 18 mA, and within seconds you can be logging soil moisture.
The ML3 ThetaProbe is robust, buriable and maintenance free (environmentally protected to IP68). It can be easily installed at depth into augered holes using the optional extension tubes.
The ML3’s excellent salinity response has been characterised at EC values up to 2000 mS.m-1. It also has a wide operating temperature range, allowing it to be used at temperatures as low as -40 degrees C (non-flexing cables).
The ML3 includes a thermistor sensor for the measurement of soil temperature of soil temperature with soil moisture (probe must be fully buried).
Whether you require monitoring or testing instrumentation, rentals or service, we are where you need us to be across Canada.
