The UV-2200 UV-Vis spectrophotometer adopts the patented technology of eliminating stray light and the patented technology of the lamp-changing and peak-seeking mechanism. The simple mechanism ensures that the system has sufficient light energy and minimizes the stray light, so that the stray light of the instrument can be avoided. reach the level of less than 1 in 100,000. High-resolution signal acquisition system; high-performance weak-signal program-controlled amplification system, signal processing system composed of multi-stage filters, and high-performance analog-to-digital conversion system and other high-quality electrical systems ensure high stability of instrument operation and high measurement accuracy.
