Overview
The JINGHUA 721 visible spectrophotometer is a classic basic instrument with a high-performance 1200L/mm grating and a new C-T monochromator structure. It features high resolution, high luminosity linearity, and low stray light. The instrument abandons the old pointer mode and uses an LCD digital display to provide higher Test accuracy and Stability. It is a cheap and durable product.
Features
1. High-performance 1200L/mm grating and C-T new monochromator structure
2. Imported Tungsten Lamp and High Sensitivity Photoelectric Converter
3. High resolution, high luminosity linearity, low stray light
4. LCD digital display, abandon the old pointer mode
5. Test accuracy and Stability
6. Classic basic model, cheap and high quality
7. Durable
Principle
The instrument adopts a new C-T monochromator structure, and separates the Illuminant into monochromatic light through a high-performance 1200L/mm grating. Imported tungsten lamps provide stable Illuminants, high-Sensitivity photoelectric converters detect the absorption of light by samples, and accurately measure parameters such as transmittance, Absorption and concentration through the liquid crystal digital display system.
Applications
Chemical analysis, biological testing, environment monitoring, food inspection, pharmaceutical research and development, teaching experiments
Steps
1. Turn on the preheating instrument
2. Set the required wavelength parameters
3. Put in the blank sample for zeroing.
4. Put in the sample to be tested for measurement
5. Read the test results on the LCD screen
6. Record or output data
Notice
• Please read the instructions carefully before use
• Avoid violent vibration of the instrument
• Optical inspection parts are kept clean
• Regularly calibrate the instrument
• Clean the sample room in time after use
• Use under specified environment conditions
