The DMM600 measures volumetric water content of organic forest floor material. It is a portable, battery-powered device that uses measurement methods sensitive to the dielectric properties of the material being measured.

The DMM600 consists of a cylinder that houses the electronics, a sample chamber with a compression knob, and an LCD readout. To measure duff water content, the sample is placed in the sample chamber and the compression knob is turned until an audible indicator signals 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 comes with a sieve and case. The sieve fits in the opening of the sample chamber. Duff is moved through the wire mesh of the sieve to break up large fragments and improve measurement accuracy in duff materials with a large range of fragment sizes. The case eases transport and provides storage for the sieve and small items such as a spare battery, screwdriver, and pencil.
