The HT-4000F is a stand-alone thermo-hygrometer for flooring installers and inspectors. The HT-4000 offers the latest in features and functionality. The meter is straightforward to operate, measures ambient temperature, relative humidity, and calculates dew point, absolute humidity (grains per pound), and vapor pressure. The meter has a detachable sensor makes the HT-4000F optimal for testing concrete slab according to the ASTM F2170 standard. It has the same rapid acclimating RH/T sensor found in our popular TotalCheck 3-in-1 moisture meter. For flooring contractors who prefer having separate meters to one combination meter, the HT-4000F is the perfect solution.
