Product Details

UV Vis spectrophotometer
1.It is a device that accurately measures electromagnetic energy at a specific wavelength of light. It uses the properties of light and energy to identify colors and determine the amount of each color in the light.

2.It is widely used in chemical analysis of gold, drugs, food industry, medicine, health, chemical industry, schools, biochemistry, petrochemical industry, quality control, environmental protection and research laboratories, etc.

Characteristics

The inssrument uses 800 x 480 true color liquid crystal display, which can store 240 standard curves and 240 data per standard curve.

The instrument host has USB2.0 data export function and supports PCL type USB printer to print A4 paper.

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.
