产品描述
The instrument:
725S visible spectrophotometer is a miniature instrument of new generation, using 128 * 64 dot matrix 3 inch LCD display, Chinese menu and online tips, with more friendly operation and improve the ability of human-computer interaction information display error. This instrument can directly use the least squares calibration, with internal 2K power protection memory, can save a plurality of test parameter files, easy to use, can be used such as statistical analysis, data processing and tabulation etc..
Use the instrument:?
725S visible spectrophotometer is convenient, stand-alone operation functions, the choice of medical health, clinical examination, biochemistry, petroleum chemical industry, environmental monitoring, quality control and other departments for qualitative and quantitative analysis
Characteristic：
128 * 64 * 3 inch LCD dot matrix display, Chinese menu and status prompt, friendly, clear interface, error information when prompted, with digital keys for calibration can directly use the least squares method.
* 2K with power-off protection memory, convenient save multiple files and test files parameter equation.
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.
