Uv/vis spectrophotometer price china with certificated
N4S / N4 UV-Vis spectrophotometer, combined with ARM processing core, automatic wavelength so that the instrument has a high-end instrument test speed and function. Which can meet the qualitative and quantitative analysis of the vast majority of UV-visible spectral ranges in conventional laboratories. Suitable for medical and health, clinical testing, biochemistry, petrochemical, environmental protection, quality control and tertiary institutions and other departments.
main feature:
7-inch color touch screen and patented technology to achieve a simple and effective human-computer interaction at the same time, clearly show the test data and scan results.
USB communication port and optional UVwin8 UV spectrum software, to achieve data and map processing functions, as well as massive data storage, and for the customer's secondary development to facilitate.
Full-band scanning (limited to S), sub-band scanning (limited to S), dynamic time scanning, automatic wavelength, linear regression, concentration direct reading, peak and valley detection, timing printing and other functions.
advanced power protection measures, you can remember the test data, scan map (limited to S models), regression equations and instrument correction parameters, to achieve rapid initialization.
With halogen and lamp life protection.
