During the application of a coating, the presence of moisture in the environment, or on the work surface, often results in a poor quality finish.
Problems such as poor adhesion of the coating or premature corrosion of the substrate can occur.
To determine the likelihood of moisture affecting the quality of the finish, it is essential that the surface temperature, air temperature, relative humidity (RH) and dew point are all measured.
The Elcometer hygrometers are designed to determine the dewpoint and relative humidity at any given time.
The Elcometer 116A Whirling Hygrometer is available in Celsius scale. A guide for Relative Humidity (RH) determination is supplied with each instrument and the dewpoint can accurately be obtained using the
