Print report in Chinese and English
Automatic search connection method, no need to manually determine which communication port to use
It is applicable to all computer operating systems of Microsoft, WIN95,WIN98,NT,WIN2000,XP..
2、 SD-2020 Hardware performance
Double pass "external" 24 bit high-precision "" chromatographic data collector. The built-in MCU control, independent power module design and USB power supply greatly improve the resistance and reduce the electronic interference to the zen low point. Standard RS-232 communication mode is adopted. The "auto triggered" start sampling function is convenient for your use. The photoelectric isolation interface ensures the safe connection with various types of chromatographs. Network card plug-in interface and automatic channel detection light make installation and fault diagnosis easy.
