Digital gloss meter principle, application and purchase guide | SKZ

A digital gloss meter is a precision instrument used to measure the gloss of an object's surface. Its principle is based on light reflectivity: a standard light source is irradiated at a fixed angle (such as 20°, 60°, 85°) onto the surface to be measured, and the intensity of the reflected light is received by the sensor to calculate the gloss value (unit: GU, Gloss Unit).

Why is gloss measurement so important?

Gloss directly affects the appearance quality of products (such as the visual effect of automotive paint and packaging printing).

It is a key indicator for quality control (such as international standards ISO 2813 and ASTM D523 in the coatings and plastics industries).

It helps optimize production processes (such as adjusting polishing parameters and coating uniformity).

Core Advantages of SKZ68

Three-angle measurement (20°/60°/85°) covers the full gloss range (matte to glossy). Portable design, suitable for rapid testing in the laboratory and on-site.

Main Application Areas of Digital Gloss Meter

SKZ68 gloss meter is widely used in the following industries:

Coatings and coatings

Detect the specular reflection performance of automotive paint and furniture coatings.

Evaluate the surface finish and durability of anti-corrosion coatings.

Plastics and packaging

Control the gloss consistency of injection molded parts and films (such as cosmetic bottles and food packaging).

Printing and paper

Ensure that the visual effect of printed materials (magazines, labels) meets brand requirements.

Metal processing

Quantify the quality of polishing or brushing process of stainless steel and aluminum alloys.

FAQ

Is it necessary to measure at three angles?

Yes! Different gloss ranges need to correspond to the best angle: 20° angle: high-gloss surface (such as piano paint, metal coating). 60° angle: general purpose (most coatings, plastics). 85° angle: matte surface (such as frosted leather, low-gloss paper).

Can SKZ68 measure curved surfaces?

It can measure curved surfaces with a curvature radius of ≥30mm. When measuring, make sure that the measuring hole is completely in contact with the surface.

Technical Advantages of Digital Gloss Meter

✅ High precision: ±1.0 GU (60° angle), meeting ISO 2813 standard.
✅ Portable and efficient: weighs only 300g, and can measure 500 times continuously on a single charge.
✅ Intelligent calibration: built-in automatic calibration board, supports one-click calibration to avoid human error.
