Product Introduction:

The DV-5020 model successfully meets the strict requirements for high-precision and high-reliability measurements. It can satisfy the demands of various applications and can be used in fields such as biological research, bioindustry, 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 design is optimized, ensuring better performance, stability, and durability of the instrument;

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

All core components use imported parts, and all optical mirror surfaces are coated with SiO2 protective film. Combined with a fully sealed monochromator structure, the instrument provides more accurate analysis, as well as improved stability and lifespan.

The independently designed socket-type tungsten lamp allows for lamp replacement without optical adjustments, making equipment debugging and maintenance simpler and more convenient.

Instrument Features:

 Chinese-language main operating system with menu display; spectral graphs can be displayed directly. Simple, convenient, and efficient to use.

Data storage function: large memory capacity meets the storage requirements for daily standard curves and experimental data. Supports external USB storage and file transfer, with printer control via USB port through software, allowing direct printing of data and graphs, as well as editing test reports.

Optional accessories according to user requirements include single-cell holder, manual four-cell holder, automatic eight-cell holder, glass holder, 1cm cuvette holder, 5cm cuvette holder, etc.

 Rich measurement methods including wavelength scanning, time scanning, and multi-wavelength determination to meet different customer measurement needs.

 Can be controlled via PC software for spectral scanning, time scanning, and more flexible measurement requirements.
