Introduction:
The instrument is the bench-top spectrophotometer with excellent repeatability, which is with auto calibration function to guarantee the short term and long-term repeatability even after drastic changes in the environment.
Advanced automatic calibration technology greatly improves long-term repeatability of instruments. Under constant temperature, the dE*ab of day 1 and day 30 can still reach 0.015. At any temperature change from 0℃ to 40℃, dE*ab can reach less than 0.1.
