Key Features - General MMD900 User Manual

The biggest advantage of the pinless sensor is its ability to sense moisture up
to 2 in. below or behind the surface of a material. The stainless steel test pins
of the MMD900 can also sense moisture just below the surface of some
materials. However, for hard materials like wood, measurements made by the
meter's test pins mostly represent surface moisture content.
For softer materials like soil, paper or powders, pin measurements are more
likely to reflect the average moisture level of the material between its surface
and the penetration depth of the pins (usually far less than 0.6 or 0.4 in.).

KEY FEATURES

• Pinless mode measurement depth of 2 in. below surface
• Displays %WME and relative readings simultaneously on two displays:
0 to 99.9 count jumbo LCD with 0.9 in. (23mm) digits, and 40-dot tri-color
LED bar graph
