Product Introduction:

The DU-6020 model successfully meets the strict requirements for high-precision and high-reliability measurements, capable of meeting the demands of various applications. It is suitable for fields such as biological research, bio-industry, drug analysis, pharmaceuticals, educational research, environmental protection, food hygiene, clinical testing, and public health.

By utilizing microcomputer technology and an electronic control system, the traditional optical path structure is optimized, ensuring better instrument performance, stability, and durability.

Highly automated functions including instrument self-diagnosis and calibration recovery ensure stable operation and reliable test data.

All core components are made of imported parts, and all optical mirror surfaces are coated with SiO2 protective film. Combined with a fully sealed monochromator structure, this enhances instrument analysis accuracy, stability, and service life.

The independently designed plug-in tungsten and deuterium lamps eliminate the need for optical adjustment when changing lamps, making equipment debugging and maintenance simpler and more convenient.
