Table top spectrophotometer TS-A12

The table top spectrophotometer TS-A12 features multiple measuring calibers, including the largest caliber of 25.4 mm, catering to the measurement needs of samples of varying sizes. It is capable of accurately measuring the color data of opaque samples, as well as the transmission and opacity of transparent or semi-transparent samples. Equipped with dual light path spectral analysis technology, it ensures precision and long-term stability of the instrument. The 8°/diffused illumination geometric design of lightning provides comprehensive insight into the color data.
