Basic Knowledge of Gloss Meter

The measurement principle of the gloss meter 

The light source G emits a beam of light through the lens L1 to reach the measured surface P. 

The measured surface P reflects the light to the lens L2, which converges the beam to the photovoltaic cell located at the optical cable B. 

The photovoltaic cell performs photoelectric conversion and sends the electrical signal to the processing circuit for processing. 

Finally, the instrument displays the measurement result.

Generally speaking, there are several specifications for glossiness meters with angles of 20 °, 45 °, 60 °, 75 °, and 85 °. 

A commonly used gloss meter is 60 °, suitable for most glossiness measurements. 

For products with a glossiness higher than 80Gu, a 20 ° glossiness meter is generally used. 

The 45 ° glossiness meter is mainly used for measuring the glossiness of plastic film surfaces, 

while the 75 ° meter is used for measuring the glossiness of copper cardboard, coated paper, and other similar materials. 

Among the mainstream standards for gloss detection are 20 °, 60 °, and 85 °.

Glossmeters can be classified into single angle, double angle, and triangle angle based on their functionality
