The MP905 extends the measurement depth of the instruments to 5 inches—the length of the MP905’s twin probes. Like the pins on the MMD900 or any pintype moisture meter, the twin probes sense the resistance between them and convert that resistance to a voltage. Circuits inside the MMD900 and MMD950 read that voltage as a proxy for the moisture level of the underlying wood or building material.


  • Length of Twin Probes: 5 in. (127mm)
  • Diameter of Probes: 0.14 in. (3.6mm)
  • Probe Hardness: 60 HRC (Hardness Rockwell “C” scale)
  • Probe Covering: Heat shrink tubing
  • Probe Tips: Rounded and replaceable (screw-in)
  • Length of Probe Cable: 56 in. (1.4m)
