The HT-4000’s advanced RH/T sensor acclimates quickly to ambient temperature and humidity, using the same technology as our popular Total CheckTM and Navigator ProTM 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 Features include:

• RH Sensor – conforms to ASTM F-2170 standard for in-situ concrete testing


• Measures Relative Humidity (RH) and temperature


• Calculates Grain Per Pound (GPP) / Grains Per Kilogram (GPK)


• Calculates vapor pressure in terms of Pounds per Square Inch (PSI) / Kilopascals (KPA)


• Back lit display – makes it easy to read in dark areas


• HOLD function – freezes readings on screen for later viewing

Applications include: Flooring Installation, Restoration,
Home Inspection, and General Contracting
