Delmhorst HT-4000 Thermo-Hygrometer

The Delmhorst HT-4000 is a stand-alone thermo-hygrometer for flooring installers and restoration contractors alike. The HT-4000 has the same fast acclimating RH/T sensor found in the popular TotalCheck and Navigator Pro 3-in-1 moisture meters. For contractors who prefer having separate meters to one combination meter, the HT-4000 is the perfect solution. The meter's sensor is also detachable, making the HT-4000 ideal for testing a concrete slab according to the ASTM F2170 standard.
