简单介绍
755S UV VIS spectrophotometer with a large screen and high brightness LCD display screen, Chinese menu and online parameter prompt, power-off protection, host direct least squares calibration model of
产品描述
* 128 * 64 dot matrix 3 inch LCD screen, Chinese menu and status tips, with 2K Byte power-off protection memory can save 18 sets of test parameters and linear regression equation. Decimal keyboard input, the host can direct least squares calibration, establish linear regression equation.
Using the original Japanese Hamamatsu L2D2 series of high stability, high brightness, not less than 3000 hours of working life of deuterium lamp, Japan original 10000 hour long tungsten lamp, Hamamatsu 1226 ultraviolet receiver; patent technology combination light technology and high stability and reliability.
This is a RS232 serial port, optional dedicated data processing software package extended quantitative analysis functions such as plug-in or serial printer.
By manually adjusting the wavelength 100% and 0; automatic adjustment; transmission ratio and absorbance, concentration factor set and concentration direct reading.
This compact, weight 7.5kg, suitable for modern laboratory environment and carry mobile.
This sample room to accommodate 4 position cuvette shelf, user selectable 1-5cm optical path rectangular cuvette.
