ThetaProbe Soil Moisture Sensor - ML2x

• ±1% accuracy
• Easy data logger connection (DC in DC out)
• Excellent temperature and salinity stability
• Dual purpose: either hand-held for spot readings or left in-situ for data logging

With the ThetaProbe it's easy to make reliable, accurate soil moisture measurements. Simply insert the probe into the soil, connect to your data logger or meter, provide 5-15V DC at 20mA, and within seconds you can be logging soil moisture.

ThetaProbes are robust, buriable and maintenance free. They can be easily installed at depth in the soil by inserting them into augered holes using the optional extension tubes.

ThetaKit

This portable kit contains all the items needed to make rapid spot readings of soil moisture content with a ThetaProbe. The Thetakit includes an Moisture Meter type HH2, spare ThetaProbe rods, insertion kit and carrying case.

Applications

Typical application areas include irrigation, hydrology, civil engineering, soil water profiling, pollution monitoring and forestry. Because the ML2x has a predictable saline response (which actually declines as salinity increases) it can be used even in very saline soils - up to 2000 mS.m-1. The ThetaProbe is not limited to the measurement of soil moisture content - it is also used in non-soil media; please enquire for further details.

ThetaProbes are the result of collaborative development with the Macaulay Land Use Research Institute (MLURI). Please click on the MLURI link, below, to visit the ThetaProbe pages of the MLURI web site.
