Elcometer 308 Hygrometer

Quantity Order:

Before painting it is necessary to check that the climatic conditions are suitable for the coating being applied. These are clearly specified on the paint manufacturer’ s product data sheet.

Surface temperature ( Ts) and Relative Humidity ( % RH) are two key climatic values which are specified on many data sheets.

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. Typical maximum RH values specified by paint manufacturers are between 75% and 85% .

The Elcometer 308 Hygrometer has been specifically designed for use in very hot climates where the surface temperature of the substrate can exceed the paint manufacturer’ s recommended limits for successful painting Surface Temperature ( Ts)

Painting outside recommended limits can have a detrimental affect on the performance and lifetime of the coating. The Elcometer 308 Hygrometer provides a simple and fast measurement of these two critical parameters.

Rugged design: Suitable for use in extreme environments the Elcometer 308 is dustproof and waterproof with fully sealed sensors.

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

Backlight: Bright screen making information easy to read – ideal in dark or confined spaces.
