N4 (754N) UV visible spectrophotometer, combined with ARM processing core, automatically wavelength enables the instrument to have the testing speed and function of high-end instruments. It can meet the quantitative analysis of most samples in the UV visible spectral range in conventional laboratories. Suitable for application in departments such as medicine and health, clinical laboratory, biochemistry, petrochemicals, environmental protection, quality control, and colleges and universities.
A 7-inch color touch screen and patented technology enable simple and effective human-computer interaction while displaying test data clearly and distinctly.
Equipped with an optional thermal printer, it enables printing and output of test results, facilitating the formation and storage of data reports.
USB communication port and optional UVWin8 software package enable data and graph processing functions, as well as storage of massive data documents, and provide convenience for customers' secondary development.
Automatic wavelength, fast and precise.
It has functions such as dynamic time scanning, automatic wavelength, linear regression, concentration direct reading, peak valley detection, and timed printing.
Advanced power-off protection measures can memorize detection data, regression equations, and instrument correction parameters, achieving fast initialization.
