It takes the "all-in-one" concept to a whole new level.


Introducing the Protimeter MMS2, the world's most advanced all-in-one moisture meter.

The attachments aren’t just included, they’re built in.


The Protimeter MMS2 is the industry’s most advanced all-in-one moisture meter. Its ergonomic, 4-in-1 design allows one-handed operation to measure moisture on and below the surface as well as ambient air humidity. With an infrared thermometer to calculate the difference between dew point and surface temperature, this meter is designed to assess moisture in both new and refurbishing projects, as well as to diagnose moisture-related problems in existing buildings.


All Protimeter instruments have a two-year warranty.
