Overview
The DMM600 is a portable, battery-powered duff meter that accurately measures moisture content in duff material, which is critical to those conducting scheduled burns as well as those attempting to battle out-of-control fires. The DMM600 is a stand-alone device. (A data logger is not required.) A sieve, carrying case, and software are included.
Key Advantages
Measures duff water content in the field
Technical Description
The DMM600 uses measurement methods sensitive to the dielectric properties of the material being measured. It consists of a cylinder that houses the electronics, a sample chamber with a compression knob, and an LCD readout.
To measure duff water content, place the sample in the sample chamber and turn the compression knob until an audible indicator signals that the sample is properly compressed and the measurement is complete. Total time for measurement is about 30 seconds. Readings are displayed in real-time only; measurements are not stored.
The DMM600 was developed in cooperation with the USDA Forest Service, Rocky Mountain Research Station, and Missoula Technology and Development Center.
