Overview
The QIWEI WFH-204B portable UV analyzer is composed of quartz Glass UV tubes and filters, and provides two sets of wavelength Illuminants at 254nm and 365nm. The Illuminant can be used for experiments by filtering the color of the filter, and the two Illuminants can be used alone or mixed at the same time. The whole machine has a simple structure, lightweight, strong versatility of parts, and convenient use and maintenance.
Features
1. Quartz Glass UV lamp and filter
2. Provide 254nm and 365nm Wavelength Illuminants
3. Illuminants can be used alone or mixed at the same time
4. Simple structure, lightweight, and versatile parts
5. Easy to use and maintain
Principle
The instrument is composed of quartz ultraviolet lamps with wavelengths of 254nm and 365nm and color filters. Illuminant is used for experimental detection after being filtered by filters, and the samples are excited by ultraviolet rays to generate fluorescence for substance analysis.
Applications
Scientific experiments, production research, dyestuff coatings and rubber, petrochemistry, Spinning & weaving chemical fibers, grains, oils, vegetables and food, public security certificate identification
Steps
1. Connect AC220V +/- 10% 50Hz power supply
2. Select 254nm or 365nm Wavelength Illuminant, or use both
3. Place the sample in the instrument detection area
4. Observe the fluorescence reaction for analysis
