The DA8 is a battery operated, hand held moisture meter designed for laboratory or in plant test conditions. It can test materials with a fairly constant bulk density and a consistent change of radio frequency properties with change in moisture content, including semisolids, powdered, granular, or textile materials. Great for all types of coffee beans at all relevant moisture levels, especially for non destructive
moisture determination of green coffee beans through burlap coffee sacks.
Operating on the patented radio frequency power loss absorption principle, the DA8 projects an RF Field in to the test area. The RF Field extends approximately three inches from the electrode needles. Any material containing moisture will absorb part of this current and cause a change in the meter readings. The meter reading is converted in to moisture content by referring to a pre-programmed calibration curve established for the material being tested.
WHAT MAKES THE DA8 DIFFERENT?
The use of solid state sensitivity modules gives the DA8 a uniquely broad moisture range capability. The modules permit more sensitivity in low moisture ranges, as well as the ability to check high moisture content.

The needle electrode consists of two 3/16th" tapered stainless steel needles, positioned 3/4 inch apart.
Longer needles test and average more sample, and yield steeper calibration curves. Three different sizes are available for coffee sacks,
depending on the most suitable configuration for the application.
