Stand-alone thermo-hygrometer for flooring installers and restoration contractors
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
  • 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

Outstanding Features & Benefits

  • detachable RH sensor
  • conforms to ASTM F-2170-02 standard
  • can connect to optional cable for easy viewing while inserted in concrete

  • large, legible LCD screen
  • streamlined interface allows for out-of-thebox ease-of-use

  • rugged design that will help to ensure years of reliable use

RH/T-S1: Replacement relative humidity sensor, great for checking in multiple locations on a concrete slab.

CS-2, CS-3: Plastic sleeves come in 2” (CS-2) and 3” lengths (CS-3), and are scored for easy depth adjustment.

The HT-4000 is great for testing the RH of concrete using the ASTM F-2170-02 standard, or for monitoring the drying process
