Overview
The YUE FENG 722S visible spectrophotometer is a precision opticalin strument with a new microcontroller system. It has the characteristics of powerful function, small size and easy maintenance. It adopts a flame retardant insulating all-plastic shell, which has a beautiful shape, convenient operation and high safety factor.
Features
1. Adopt a new type of single-chip microcomputer system, with strong functions, small size, and easy maintenance.
2. The use of flame retardant, insulated plastic shell, exquisite design, easy to operate, high safety factor.
3. True 4-bit LCD display, Measurement range, high calculation accuracy.
4. Membrane keyboard, good feel, dustproof, waterproof and easy to clean.
5. Professional Optical inspection system design, sealing grating monochromator, adopt scientific anti-mildew technology, eliminate stray light technology, significantly improve the service life, stray light, Stability, metering accuracy indicators.
6. Use a lens to concentrate light to avoid a straight drop in energy after the reflector has been ablated for a long time.
7. Special precision lamp holder, can replace the halogen tungsten lamp without having to adjust the light path again.
8. Automatically adjust 0%, automatically adjust 100% and Absorption OA.
Principle
Optical inspection system of single beam of light is adopted. Based on the principle of light absorption, a sealing type grating monochromator is used to select a specific wavelength ray of light to measure the transmittance or Absorbance of the sample to light. Automatic calibration and concentration calculation are realized by using single chip microcomputer system to process data.
Applications
Chemical analysis, biological testing, environment monitoring, pharmaceutical research and development, food inspection
Steps
1. Turn on the preheating instrument.
2. Set the desired wavelength.
3. Put in the blank sample and automatically adjust it to 0% and 100%.
4. Put in the sample to be tested and read the transmittance or Absorbance value.
5. For concentration measurement, set the concentration factor or read the concentration value directly.
6. Connect the PC software through the RS232 interface for data transmission.
Notice
• Make sure the instrument is placed on a stable, vibration-free workbench.
• Optical inspection components are cleaned regularly to avoid dust affecting Measurement accuracy.
• Use a special precision lamp holder when replacing the halogen tungsten lamp, no need to adjust the optical path.
• Avoid prolonged exposure to bright light or humid environments.
• Use a power supply that meets specifications to prevent voltage fluctuations from affecting instrument performance.
