The Elcometer 308 Hygrometer has been specifically designed for use in veryhot climates where the surface temperature of the substrate can exceed the paintmanufacturer’s recommended limits for successful painting.Painting outside recommended limits can have a detrimental affect on theperformance and lifetime of the coating. The Elcometer 308 Hygrometer provides asimple and fast measurement of relative humidity and surface temperature.
The Elcometer 309 Delta T Hygrometer provides a simple and fast measurementof the two critical climate parameters within coatings:
Delta T (TΔ): The difference between the surface temperature (Ts) and thedewpoint temperature (Td). When TΔ is less than 3ºC (5ºF) painting should notoccur.
Relative Humidity (RH): This is the amount of water vapour taken up by air.Expressed as a percentage, RH is dependent on the air temperature.
Strong design: Elcometer 308 Hygrometer is dust-resistant and waterproof equipped with sensors.
Function of Holding Measurement Results: With one button, the reading results from the tool will be 'held' on the screen. It can then be recorded before pressing the button again to ‘release’ the screen and continue to capture further necessary data.
Background light: Bright screen makes information easy to read – ideal in dark spaces.
