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 MeasurementDesigned 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.

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 BenefitsIdeal 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.
FAQs of Reflectance meter:
Q: How is a reflectance measurement performed using this meter?
A: To measure reflectance, place the specimen securely in the precision clamp of the sample holder. After powering on and calibrating the device with the supplied white and black tiles, initiate a manual measurement. The result is displayed digitally in less than two seconds.
Q: What is the recommended operating environment for the Reflectance Meter?
A: The meter operates optimally in environments with temperatures ranging from 10C to 40C and humidity up to 85% RH. It should be used on a stable bench-top surface with a power supply of 230V AC, 50 Hz.
Q: When should calibration be performed on the device?
A: Calibration should be conducted prior to each measurement cycle or whenever accuracy needs confirmation. Use the supplied white and black tiles to ensure the device delivers precise readings for all tested materials.
Q: Where is the RS-232 interface located and what is its use?
A: The RS-232 interface is located at the rear of the meters housing. It allows users to connect the device to computers or data logging systems for efficient result processing and record management.
Q: What types of samples can be measured with this reflectance meter?
A: This meter is compatible with surfaces, textiles, papers, and paints, accommodating specimen diameters up to 50 mm. It is ideal for color and reflectance analysis in laboratory, production, or research settings.
Q: How does using this meter benefit quality control processes?
A: By providing rapid, accurate, and reproducible reflectance readings, the meter enhances the consistency and reliability of color and surface evaluation. This supports improved quality control and material assessment across industries.
