The tough, lightweight DMM600 is a portable, battery-powered sensor that provides real-time water content measurements of non-homogenous material. This sensor was originally developed to measure forest floor duff (decomposing organic material) moisture content and thus, aid in the timing of prescribed fires.

However, the DMM600 has been found to be useful with other organic materials such as compost, silage, wood waste, and saw dust. It has also been used successfully to measure the water content of mineral soil during road construction. Given the rough field environment ...
