Streamlined exterior design.
Adopt blue screen liquid crystal display module, menu display mode, humanized operation.
Simple operation, wide range of light measurement and high cost performance are more suitable for use in various industries.
The unique positioning structure and high-precision optical path system effectively ensure the stable operation of the instrument for a long time.
According to different ranges, multi-point calibration is adopted to meet the needs of different users.
The built-in printer is convenient for users to print in real time.
The chromaticity compensation system is added to effectively avoid the interference caused by the color of the sample, and can correctly reflect the concept of turbidity.
