DewCheck IV Series 2

Standards: ISO 8502-4, BS 7079-B4, NACE RP prop 97, IMO MSC.215 (82), IMO MSC.244 (83), US Navy NSI 009-32, US Navy PPI 63101-00

DewCheck IV


The DewCheck IV Series 2 is an extremely versatile tool for measuring and recording all climate parameters required for treating surfaces. This easy-to-use and robust instrument measures air temperature, surface temperature, air humidity dewpoint and calculates the difference between the surface and dew point temperature, indicating optimum climate conditions for painting. All parameters, including time and date, are stored in the memory and can be retrieved at a later time.

  • Large illuminated graphic display
  • One-hand operation
  • Simple menu-driven user interface
  • Extensive data-logging capabilities, readings are time and date stamped and stored on the gauge
  • Used as “on the spot” inspectors tool or “stand-alone” data logger
  • Heavy duty ergonomic case
  • Set limits for each parameter
  • Acoustic and visual alarms
  • Select Celsius / Fahrenheit
  • Auto trend indicator shows the trend of climatic conditions (rising, falling, stable)
  • High-end industrial sensors and built-in probes
  • Integrated ‘back-up’ LED flashlight
  • Two year valid calibration certificate
  • For optimal use of the datalogging facilities of the instrument, the DewCheck Dock is available.




Features DewCheck IV
  • 3 strong Neodymium magnets hold instrument and dock firmly against ferrous steel surfaces. Magnets are lined with rubber to prevent damaging the surface and sliding of the unit.
  • A magnetic surface temperature sensor overrides the instrument’s integrated surface temperature sensor in order to guarantee correct TS-readings.
  • USB-Interface connects the unit to the PC for programming and downloading data.
  • 2-Year Warranty that covers everything except abuse
Note: The Dewcheck dock is indispensable for communication between Dewcheck and computer
Safety Precautions
  • Always keep the instrument in its pouch when not in use. Ensure the instrument is correctly inserted in the pouch with the display to the front.
  • The humidity sensor is fragile and should never be touched. Do not use compressed air to clean the sensors or the instrument.
