Overview
Enviro Testers Portable Medical Spectrophotometer Gloss Meter is developed with independent intellectual property rights. It features with stable performance, precise measurement and powerful functions in the leading position of the same industry. In the R&D process, our scientists and engineers measured various colour samples from dark to light, white to black, and other standard colour boards provided by ISO (International Standardization Organization). The parameters of test results are integrating with international standards. We also analysed the parameters from Japan, American and Germany spectrophotometers. The differences of Lab absolute value between them are within ±1.5. Compared the Lab value between NS810 and Japan spectrophotometer, when measuring any color objects, the biggest Lab difference is within ±1.0. This is a breakthrough of high technology which realizes to be fully compatible with international market.
