Portable Spectrophotometer
ST-810 spectrophotometer is developed by Stalwart 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, Stalwart scientists and engineers measured various color samples from dark to light, white to black, and other standard color boards provided by ISO (International Standardization Organization).
