UV-Vis Spectrophotometer model UV1902


UV1900 series double beam UV visible spectrophotometry using rigorous precision double beam optical system and a circuit control system design, high quality instrument determines the with high standards of accuracy, repeatability, low noise and low stray light index and excellent stability and linear range.

There is 1nm and 2nm two kinds of bandwidth allocation, suitable for different users to choose.

This instrument uses high-quality Heraeus preset deuterium lamp and Osram long-life halogen lamp light source, convenient replacement.

The big screen 6 inches 320 x 240 dot matrix backlit digital display LCD, the instrument is simple, intuitive.

- demolition of the structure of the sample chamber design, the user can optional reflection sample frame, solid sample frame measuring accessory, in different application areas meet the analysis requirements testing.

Windows environment in the development of software in English, provides abundant and unique analysis system.

Special analysis software:

UV1900 series dual beam UV visible spectrophotometer qualitative and quantitative data processing software, UVCON control software based on Windows environment, can control the operation of the host, including data acquisition (single point, multi-point measurement, spectral scanning, quantitative measurement, time scanning and DNA) and various data processing, to complete the analysis from the conventional quality control to environmental protection, bio chemistry, medical health, materials and other fields.
