Hygrometer Testing
(Floor RH%)

Southern Geophysical uses the Protimeter Hygromaster 2 for concrete moisture, HVAC, and building surveys

Thermal hygrometer testing allows the relative humidity RH% of a concrete slab to be accurately determined. Southern Geophysical use the Protimeter Hygromaster 2 humidity and temperature meter which deploys a multitude of different methods for measuring air and surface temperature in addition to ambient relative humidity (RH) and even equilibrium relative humidity (ERH) in concrete. 

In addition to these measurement functions, the Protimeter Hygromaster 2 tester can calculate surface proximity to dew point in addition to various other psychometric calculations. Thermal hygrometer testing can also be used to investigate dew point and condensation conditions.
