Abstract:
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 also has been used successfully to measure
the water content of mineral soil during
road construction.
Given the rough field environment inherent
to forest fire, the duff moisture meter is
designed to provide accurate results in the
field with a minimum amount of sample
preparation and measurement logistics.
