Environmental Measurement Instruments

Monitoring climatic conditions – temperature, relative humidity, dew point and moisture – is often essential to the successful application of a coating and is critical in ensuring the final quality and performance of the coated product.

Climatic conditions: Elcometer offers a complete range of dew point and relative humidity meters, thermometers, data loggers, moisture meters and anemometers for monitoring climatic conditions.

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

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