Delmhorst HT-4000 Thermo-Hygrometer


The HT-4000F is a stand-alone thermo-hygrometer for flooring installers and inspectors. The meter’s detachable sensor makes the HT-4000F ideal for testing a concrete slab according to the ASTM F2170 standard. It has the same fast 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.
