The Protimeter MMS3 with wireless capability represents the latest in moisture measurement technology. Its ergonomic 4-in-1 design allows for fast and accurate full building diagnostics both on and below the surface, from new building construction to refurbishing projects in existing buildings. Also, with built-in hygrometric capabilities and an infrared (IR) laser thermometer,  the MMS3 also assesses indoor air quality conditions.
