Before painting, the coater must meet the coatings’ parameters. These are clearly specified on the paint manufacturer’s product data sheet. Relative Humidity (RH) and Delta T (TΔ) are the two climatic values which are specified on data sheets.
Conform to ISO 8502-4, BS 7079-B4The Elcometer 309 Delta T Hygrometer provides a simple and fast measurement of these two critical characteristics.
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.
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.
