Delmhorst HT-4000




Delmhorst is proud to introduce the HT-4000, a stand-alone thermo-hygrometer for flooring installers and restoration contractors alike. The HT-4000’s advanced RH/T sensor acclimates quickly to ambient temperature and humidity, using the same technology as our popular Total Check™ 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 F-2170 standard.
