 The terms "contrast ratio", "opacity" and "hiding power" are used interchangeably throughout the coatings industry but on this page, in order to simplify matters, only the term opacity will be used. Opacity is defined as the ability of a coating to prevent the transmission of light. A practical example of this is the case where a yellow wall is painted using a red paint. The greater the opacity the red paint, the more efficient it will be at hiding the underlying yellow colour

        
Opacity is defined by how a wet film of the test coating is applied to a black and white patterned substrate. After the film has dried, a reflectance meter or a spectrophotometer is used to measure the amount of light reflected from the overcoated black areas of the substrate. This is then expressed as a percentage of the amount of light reflected from the overcoated white areas. This value is the opacity of the film.

        
A paint which is highly opaque will obscure the black and white areas to an equal extent. In this situation, equal amounts of light will be reflected from the overcoated black and white areas and consequently an opacity value of 100% will be obtained.

Fast and Accurate Reflectance Measurement

Designed for precision, the meter delivers results rapidly, with standard measurements completed in less than two seconds. Its 45/0 geometry ensures consistent accuracy across the test width of 50 mm, making it suitable for analyzing color and reflectance of various materials such as textiles and paints. Supported by 0.5% accuracy and 0.1% resolution, results are both reliable and reproducible.


Robust Construction and User-Friendly Operation

Housed in powder-coated metal, the reflectance meter guarantees durability and is CE marked for safety. The bench-top design, manual control mode, and ergonomic precision sample clamp contribute to ease of use and secure sample placement. Featuring a digital LCD display and calibration tiles, users benefit from straightforward operation and quick calibration capability.


Versatile Applications and Practical Benefits

Ideal for laboratories, exporters, and wholesalers, this equipment supports single specimen analysis up to 50 mm diameter. Its portable and compact build suits various analysis requirements, from manufacturing quality control to research. The RS-232 interface ensures easy data connectivity for further processing, while its wide operating range accommodates diverse environmental conditions.
