Bench Top Spectrophotometer CS-821N
Desk-top Spectrophotometer CS-821N to Aanalyzer Data Color of Masterbatch Granules
Part 1. Desk-top Spectrophotometer Introduction
CS-821N is the bench-top spectrophotometer with excellent repeatability. Instrument is with auto calibration function to guarantee the short term and long term repeatability even after drastic changes in the environment.
It is an smart, simple operate and high precise spectrophotometer. It adopts 7 inches touch screen, full wavelength range, Android operate system. Illumination : reflectance D/8° and transmittance D/0°(UV included / UV excluded), high accuracy for color measurement, large storage memory, PC software, because of above advantages, it is used in laboratory for color analysis and communication.
