N4S / N4 UV-Vis spectrophotometer

Introduction of spectrophotometer:
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 of spectrophotometer:
*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 deuterium lamp life protection.

Optional:
*Built-in thermal printer (N4S only)
UVwin8 UV spectrum software

Other:
*Light source: 12V 20W halogen lamp and long life deuterium lamp
*Power supply voltage: AC220V ± 22V 50Hz ± 1Hz
*Power: 180W
