Be confident in your purchase, we're an Authorized PCE Instruments Dealer. Highlights: For non-stationary use Measurement up to 200 gloss points 60 Measurement geometry 3.5" TFT display Quick measuring time of 0.5 seconds The PCE GM 60 Plus Gloss Meter is a measuring device for the determination of gloss on different materials. During the measurement, the gloss tester picks up the reflection of emitted light. The light is emitted directly by the gloss tester. Part of the light is then reflected off the surface to be measured and part of the light is absorbed by the surface. Thanks to the reflected light, the gloss tester then calculates the degree of gloss and displays it clearly on the TFT display. The gloss tester is used in areas where it is essential that individual products always have the same appearance and texture and properties. In this way, complaints and associated costs are avoided. In addition, the external reputation of companies with consistent quality and consistent products is respected or improved.
