Kit for surveying and inspecting moisture in buildings

The Tramex BSMK is the ultimate kit for non-destructive testing of moisture content and humidity conditions in drywall, wood, plaster, brick, ceramic tiles, resilient flooring, laminates and roofing and numerous building materials and air spaces. Tramex moisture meters are designed to locate elevated moisture & humidity conditions, which may be conducive to mold, microbial growth and wood destroying organisms. These damp conditions can often be hidden within or behind a material such as drywall and not obvious from visual inspection without the help of a non-destructive moisture meter. Once the moisture source is identified and stopped, remedial action can be taken leading to a healthier building environment. The Tramex RWS Roof & Wall Scanner allows for for instant, non-destructive evaluation of moisture conditions deep within wall and roofing systems.The Tramex digital MRH III and reusable Ambient Relative Humidity Hygro-i2 Short Probe allow for testing relative humidity, temperature and dew point in the environment. The heavy-duty pin-probes measure moisture content in wood, and the insulated 7.8" (200mm) pins allow for deep wall cavity probing. Concrete slab in situ relative humidity testing can also be performed with the reusable relative humidity probe and enclosed hole liners. The Tramex Building Survey Inspection Kit comes in a protective heavy-duty carrying case with die-cut foam lining.
