Overview
The JINGHUA 722S visible spectrophotometer is a high-performance analytical instrument with a C-T monochromator structure, 1200L/mm grating, imported tungsten lamps and high-Sensitivity photoelectric converters to ensure high resolution, high luminosity linearity and low stray light, providing stable test performance. The instrument has T, A, C, F and other functions, and can be equipped with special software to enhance Data analysis and storage capabilities.
Features
1. High-performance 1200L/mm grating and C-T monochromator structure ensure high resolution, high luminosity linearity and low stray light.
2. Equipped with Imported Tungsten Lamp and High Sensitivity Photoelectric Converter to Improve Test accuracy and Stability.
3. Large sample chamber, with a maximum optional 100mm sample holder, to meet the needs of different industries.
4. It has various functions such as T, A, C, and F.
5. Optional special software to achieve multi-angle Data analysis, storage and retrieval is more convenient.
Principle
The instrument is based on the Spectrophotometric method, spec-trophotometry principle, and the Illuminant is separated by the C-T monochromator structure, and the 1200L/mm grating and imported tungsten lamp are used to generate monochromatic light. After the sample is absorbed, the transmitted light intensity is detected by the high-Sensitivity photoelectric converter and converted into electrical signals for processing, so as to measure parameters such as transmittance, Absorbance and concentration.
Applications
Chemical analysis, biological testing, environment monitoring, pharmaceutical research and development, food inspection
Standards

Steps
1. Turn on the preheating instrument.
2. Set the wavelength parameters.
3. Place the sample in the sample chamber.
4. Select Measurement mode (T, A, C or F).
5. Take measurements and read data.
6. Data storage and analysis with optional software.
Notice
• Ensure that the instrument is used in a stable environment.
• Regularly calibrate wavelength and transmittance accuracy.
• Keep the sample room clean to avoid contamination.
• Turn off the power supply in time after use.
• Optional accessories must be properly installed and used.
