DELMHORST Digital Soil Moisture Meter

Accurate soil moisture measurements are critical for determining proper irrigation rates for higher crop yields and effective plant growth. The Delmhorst moisture tester uses a series of gypsum blocks and wire leads placed at various depths to produce a profile of available soil moisture. Each block is constructed of gypsum cast around stainless steel electrodes to obtain maximum uniformity and fast response to changing moisture conditions. The digital meter is housed in a rugged ABS plastic case and features temperature stable semi-conductor technology, calibration checks, large LCD and spring loaded binding posts for positive contact with the gypsum block leads. To use, bury several blocks in representative areas to monitor changes in the area of active root growth at one or more levels. To read the available moisture, simply attach the wire leads to the terminal posts on the meter. Readings can be converted to soil moisture or moisture tension with the included operating instructions.
