Product Introduction:

The DU-5020 model successfully meets the strict requirements for high-precision and high-reliability measurements, satisfying the needs of various applications. It can be used in fields such as biological research, bio-industry, pharmaceutical analysis, drug manufacturing, educational research, environmental protection, food hygiene, clinical testing, and public health.

By utilizing microcomputer technology and an electronic control system, and optimizing the traditional optical path design, the instrument ensures greater reliability, stability, and durability.

The highly automated instrument features automatic diagnostic and calibration recovery functions to ensure stable operation and accurate test data.

All core components use imported parts, and all optical mirror surfaces are coated with a SiO2 protective film. Combined with a fully sealed monochromator structure, this ensures more precise analysis, enhanced instrument stability, and a longer service life.

The self-designed socket-type tungsten lamp and deuterium lamp eliminate the need for optical adjustments when replacing lamps, making device setup and maintenance simpler and more convenient.
