Product characteristics
The instrument uses 800 x 480 true color liquid crystal display, which can store 240 standard curves and 240 data per standard curve.
Data Output: The test data on the host can be exported directly from the U disk, and the measured data can be output through the printer with RS232 (RS485 and USB optional) interface.
Imported environmentally friendly deuterium lamp system can effectively reduce your ozone uptake
Advanced control system monitors the service life of deuterium lamp and tungsten lamp in real time
Unique socket deuterium lamp and tungsten lamp design, no optical adjustment when changing lamp
GLP self-identification function, wavelength accuracy and photometric accuracy of testing instrument, and can issue detection report and power-off protection.
The instrument can carry out automatic wavelength correction, automatic wavelength setting, automatic switching of light source and dark current correction.
Fully sealed structure and all optical mirrors have Si02 protective film, which can reduce the influence of external gas and environment on optical components.

Customers provide instrument numbers, download upgrade packages on Aoyi website, and support one-click upgrade of U disk.
