The gloss meter performs critical tasks for organizations who need to monitor surface shine and product quality. Companies use gloss meters to measure surface brightness and check product quality across various shiny materials.
Understanding Gloss Measurement
Gloss is the capacity of a surface to reflect light in a more or less specular manner that is towards a small angle relative to the incident light. The reflected wavelengths depend on the surface roughness, the material’s refractive index, and the incidence angle of light. The magnitude of reflected light affects the gloss value, with the higher reflectivity for smooth and highly polished surface and lower reflectivity for rough or matte surface.
How Does a Gloss Meter Work?
When light strikes flat surfaces the gloss meter tracks reflected light movement. The device sends light across a defined angle onto the sample and measures the brightness of light that bounces off at the same angle on the opposite side. The gloss meter counts the gloss level of a surface by measuring the strength of light reflected from that surface.
Standard test angles at 20°, 60° and 85° help measure gloss properly according to specific gloss levels:
- 20°: High gloss surfaces
- 60°: Medium gloss surfaces
- 85°: Low gloss or matte surfaces
The selected angle allows instruments to accurately measure many types of materials and surface finishes.
Components of a Gloss Meter
A typical gloss meter comprises:
- Light Source: Produces a steady light beam in a direction at a fixed angle with respect to the longitudinal axis of the device.
- Detector: Reflects the light that falls on the surface of the object.
- Processor: Determines the gloss value proportional to the intensity of the reflected light.
- Display: Shows the gloss measurement in GU.
Advanced functions may include ability to perform measurements from multiple angles and built-in storage space and radio for data exchange.
Applications Across Industries
Gloss meters are widely used in many industries as an objective measure of product quality and surface attractiveness:
- Automotive: Evaluating the painted surfaces and ensuring that the paint colors match on the different panels of the vehicle.
- Printing and Packaging: The most significant identified problem area is the variation in the levels of ink and of the coating on the microfilm.
- Furniture and Woodwork: Compared different types of varnish and lacquer for the preferred gloss level.
- Electronics: Make sure that the gloss of the screen and casing is as per the standards set during the designs made.
Choosing the Right Gloss Meter
To choose a gloss meter evaluate these criteria:
- Measurement Angles: Choose a device with angles that meet your project needs.
- Portability: Using a handheld gloss meter for on-site measurements gives the best results.
- Data Management: Quality control processes benefit from connected data storage systems.
