Product Code : HT-4000
Brand Name : DELMHORST
Product Description
                                                                    MODEL : 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 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
