简单介绍
Through the RS232C interface, can connect computers, printers and other peripherals, using the optional software package for further expansion.
产品描述
The annual 2008-2010 spectrophotometer to national supervision of product quality throughout a period of 3 years.
Characteristic：
Having a broader spectral range, including modern near infrared colorimetric analysis and biochemical and enzymatic analysis of commonly used 340nm ~ 400nm near ultraviolet and 800nm ~ 1000nm, especially suitable for the analysis of chemistry application.
- through the RS232C interface, can link the computer, printer and other peripheral equipment, using the optional software package for further expansion.
The keyboard operation is simple and clear, can easily realize automatic adjustment, automatic adjustment of 0% (T) 100% (T) and error free tau /A transform, a factor set and set the concentration type direct reading function.
Pre - adjust the light source, module design, to provide maximum convenience for user maintenance and maintenance module.
The whole Aluminum Alloy pressure casting base, a mirror seat and a holographic grating, C-T type monochromator, aspheric optical system, will bring quality and reliable performance, stable for you.
The integration of advanced solid silicon receiver - import, V/F transform and a microprocessor, the instrument can maintain accurate determination of linear and optimal linear term.
