Product Information

The MMD950 is ideal for taking measurements where traditional moisture meters can't reach.


It features two measurement modes: pin-type (using replaceable pins at the end of a 46-inch cable), and pinless (using an integral ball sensor with up to a 4-inch measurement depth).


The design of the MMD950 keeps the hand away from the sensing area, reducing interference and ensuring more accurate measurements.



  • Two measurement modes: pin and pinless
  • Pin mode uses replaceable pins at end of 46-inch cable; pinless mode uses integral ball sensor with up to 4 inches in measurement depth
  • Displays % WME or relative readings simultaneously on two displays: 0 to 99.9 count jumbo LCD, and 40-dot tri-color LED bar graph
  • Spare pins storage compartment
  • Auto-calibrating
  • Data hold function
  • Low battery warning
  • User can set beeper sound, auto power off time, backlight function
  • Superior to flat bottom sensors by enabling the user to measure in corners, hard-to-reach, areas and narrow spaces
  • Small contact area for improved repeatability
  • Spherical sensor works on uneven surfaces and corners
  • Works at any angle
  • Can accommodate wide viewing angle
  • Keeps hand away from sensing area, reducing interference



  • Remote probe
  • 1 “9V” battery
