Automatic calibration

√（Can greatly improve the long-term repeatability of the instrument）

Fluorescence calibration

√（Can automatically adjustthe UV intensity，and ensure that the value of the instrument is highly consistent with that of other imported instruments when measuring materials containing fluorescence）

Brightness calibration

√（Through the brightness calibration algorithm, the real color of ultra-dark samples is restored）

Others

The instrument can be measured sideways,up and down (using accessories); Automatic temperatureand humidity compensation function; PC side software save sample image function
