• Rugged design
• Greater than 40 hours battery life
• Designed for hot and humid weather
• Measurement hold/release function

 

The Elcometer 308 Hygrometer has been specifically designed for use in very hot weather where the surface temperature of the substrate can exceed the paint manufacturer’s recommended limits for successful painting.

Painting outside recommended limits can have a detrimental effect on the performance and lifetime of the coating. The Elcometer 309 Delta T Hygrometer provides a simple and fast measurement of relative humidity and surface temperature.

The Elcometer 309 Delta T Hygrometer provides a simple and fast measurement of these two critical characteristics.

  1. Delta T (TΔ): The difference between the surface temperature (Ts) and the dewpoint temperature (Td). When TΔ is less than 3ºC (5ºF) painting should not occur.
  2. Relative Humidity (RH): This is the amount of water vapor taken up by air. Expressed as a percentage, RH is dependent on the air temperature. Typical maximum RH values specified by paint manufacturers are between 75% and 85%.

Rugged design: Suitable for use in extreme environments the Elcometer 309 digital hygrometer is dustproof and waterproof with fully sealed sensors.

High / Low Limits: Displayed on-screen graphically as either (?) or (X) with flashing Red or Green LED’s to indicate pass or fail.

Delta T Temperature: TΔ is pre-set at >3ºC (>5ºF), the industry norm.

Relative Humidity: User definable upper limit can be set for RH.

Measurement Hold / Release function: With a single button press readings are ‘frozen’ on the screen. These can then be recorded before, simply pressing the button again to ‘unfreeze’ the screen and then take further readings as necessary.

Backlight: Provides clearly lit information – ideal in dark or confined spaces.
