Detailed introduction:
Type N4S UV VIS spectrophotometer Is a can adapt to the modern analysis laboratory using the spectral analysis method of material spectrophotometry needs low price and high performance of qualitative and quantitative analysis of various projects. Widely used in medicine and health, environmental protection, food industry, petroleum chemical industry, biological chemistry, quality control and other departments and colleges.
N4S UV VIS spectrophotometer, combined with the ARM processing core, test speed and wavelength. The instrument has the function of automatic high-grade instrument. Can meet the qualitative and quantitative analysis of routine laboratory most UV visible spectral range of samples. Suitable for the Department of health and medicine, clinical examination, biochemistry, petroleum chemical industry, environmental protection, quality control and other tertiary institutions.
Main features:
5.6 - inch color touch screen and patented technology, realize the simple and effective human-computer interaction and clear display of test data and results.
