Overview of Delmhorst HT-4000 Thermo-Hygrometer:

The GPP Delmhorst HT-4000 is a stand-alone Thermo-Hygrometer for Concrete Floor and Flood Restoration contractors alike. The HT-4000 has the same fast acclimating RH/T sensor found in our popular TotalCheck and Navigator Pro 3-in-1 moisture meters.  The HT-4000 also provides GPP readings.  GPP is the humidity ratio measured as the ratio of the mass of water to the mass of dry air.

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 or inserting the RH sensor into a remote location.  Note that this meter does not come with an RH Cable, it is optional.
