Product Description
Delmhorst Thermo-Hygrometer w/GPP Calculation
In our continuing effort to respond to industry demands, Delmhorst is proud to introduce the HT-4000, a versatile thermo-hygrometer for flooring installers and restoration contractors alike. The HT-4000Â’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.With the ASTM F-2170 standard gaining widespread acceptance from flooring manufacturers and installers, itÂ’s more important than ever to be prepared with the right tool for the job. 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 your drying process. Using the HT-4000 and a moisture meter during the drying cycle will allow you to sign off with confidence that the structure is dry.
Like all of Delmhorst's products, the HT-4000 is proudly made in the USA.
