Gloss meter is to measure the mirror surface of the visible light reflection performance, in order to ensure the measurement of a variety of surface light on the mirror
The sensitivity of reflection and the angle of incidence of the light source of the instrument on the surface of the workpiece are designed in various angles. Commonly, there are three angles of incidence of 20 ° 60 ° 85. For the workpiece with a relatively smooth and smooth surface, 20 ° Incidence angle measurement, the workpiece surface roughness, poor reflective properties of the workpiece, the general selection of 85 ° angle of incidence measurement, between the ordinary workpiece surface between the general selection of 60 ° angle of incidence measurements.
Select the instrument, the need to select the appropriate instrument according to the surface reflection characteristics of the instrument, if you want to adapt to a variety of workpiece surface measurements, consider the purchase of three-angle gloss instrument, the instrument simultaneously detected three angles (20 ° 60 ° 85 °) Gloss value, according to process requirements of a key angle reference value.
For most common workpiece surfaces, simply select a 60 ° gloss meter.
In the purchase of gloss meter, but also need to consider whether the measurement area of the workpiece surface can cover the measurement window (bottom), if not cover the measurement window, it will directly affect the measurement results.
