The BSMK5.1 Building survey master kit is a complete kit featuring the RWS Roof & Wall Scanner for instant, non-destructive evaluation of moisture conditions deep within wall and roofing systems.

The Building Survey Master Kit features the multifunctional Tramex MRH3 digital moisture meter allowing for non-invasive testing of moisture conditions in numerous building materials such as drywall, wood, plaster, brick, ceramic tiles, resilient flooring, laminates and roofing.

The MRH III and reusable Ambient Relative Humidity Hygro-i2 Short Probe allow for testing relative humidity, temperature and dew point in the environment. When used in conjunction with the infrared surface thermome- ter, detrimental condensation conditions conducive to microbial growth can also be identified.

The heavy-duty pin-probes measure moisture content in wood, and the insulated 7.8” pins allow for deep wall cavity probing. Concrete slab relative humidity testing to ASTM F2170 can also be performed with reusable relative humidity Hygro-i2 probes and hole liners(optional).
