Elcometer Digital Dew Point Meters

The monitoring of climatic conditions such as temperature, relative humidity, dew point and moisture in industry is often vital to the success of the application of the coating. These parameters determine both the conditions for application of a coating, and the resulting quality and performance of the coated product.

In the protective coatings industry, moisture can form on the surface when the surface temperature is low enough to cause condensation from the atmosphere. The dew point temperature (Td) is the point at which this occurs.

Monitoring air temperature (Ta) and its relative humidity (%RH) allows the dew point temperature to be calculated and compared to the surface temperature (Ts). The difference in temperature (TΔ) is the key parameter dictating when it is safe to apply the coating.
