Linyi UV spectrophotometer UV755B

To meet different application requirements required. Is Youke Instruments for organic chemistry, biochemistry, pharmaceutical analysis, food inspection, medicine and health, environmental protection, life sciences and other fields of scientific research, production, the need for accurate measurement of the high demands of professional users and design, using the latest computer technology and electronic control systems, optimization of traditional optical design and structural design of the instrument, while the expansion of new features, accuracy, stability, and durability are also more assurance; Features: 1200 / mm grating performance. The new light source control system, the instrument light source switching faster. Accurate 2nm bandwidth make more accurate test data. The use of imported long-life light source, the instrument light switch faster. Specific wavelength control system, so that the wavelength accuracy higher. Improved optical system, to make the test more accurate. Imported photoelectric conversion, higher sensitivity of the instrument. The new microcomputer data processing system. Make it easier to use the instrument, stability is also very good. The instrument uses 128 * 64 dot matrix LCD display, can display standard curve and test data, the host can store test data directly, and an optional printer and operating system software with automatic fault diagnosis function to ensure the stability and accuracy of measurement instruments operating software enables remote upgrades, updates the model UV755B UV756 UV759CRT wavelength range 190-1100nm? 190-1100nm? 190-1100nm?
