Delmhorst introduces the HT-4000, a versatile thermo-hygrometer for flooring installers and restoration contractors alike. The HT-4000’s detachable RH sensor “makes it ideal for ASTM F2170 concrete slab testing or for monitoring the relative humidity of the air in a structure.”

Checking the RH of a concrete slab before installing a floor covering can mean the difference between a successful installation, or one that requires costly callbacks. For restoration contractors on a water loss, the HT-4000 can provide valuable information to guide the drying process.
