Gloss meter is a measure of the mirror surface of the visible light reflection properties, in order to ensure the measurement of a variety of surface light reflection of the sensitivity of the light source to the workpiece surface angle of incidence of the design into a variety of angles, the common 20 ° 60 ° 85 three angles of incidence, the workpiece surface is relatively smooth, high smoothness of the workpiece, the general choice of 20 ° angle of incidence measurement, the workpiece surface roughness, poor reflection of the workpiece, the general choice of 85 ° angle of incidence measurement , Between the ordinary workpiece surface between the two, the general choice 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.
