Overview
The 7230G (PC) visible spectrophotometer is an analytical instrument of the YUE FENG brand. It uses one-button automatic correction of ABS values, digital display of Measured values, and is equipped with imported tungsten lamps, with a service life of up to 2000 hours. It has a large sample chamber, can hold up to 100mm Cuvette, and supports RS232 data output port, which can be connected to computers and printers.
Features
1. Four-digit LCD liquid crystal display
2. Spacious sample room can accommodate 5~ 100mm Cuvette
3. Host can be photometric detection, with software can be Basis Weight detection, display standard Linear dispersion, C = F × ABS
4. The main components are imported for easy maintenance
5. The newly designed Czerny-Turner light path ensures the detection of linear Precision and ultra-low stray light
6. You can directly connect the printer (optional) to print data or maps
Principle
Optical inspection system, based on Czerny-Turner optical path design, achieves detection of Wavelength range 325~ 1000nm through grating spectroscopy to ensure photometric Precision and low stray light. With software, photometric measurement and Basis Weight test can be carried out, including standard Linear dispersion method and coefficient method.
Applications
Photometric measurement, Basis Weight test
Standards
Luminosity Precision ： +/- 0.002A (0~ 0.5A )、 +/- 0.003A (0.5~ 1A )、 +/- 0.5% T; Luminosity Repeatability: ≤ 0.3% T (0~ 100% T); 0.001A (0~ 0.5A); 0.002A (0.5~ 1A); Stray Light: ≤ 0.3% T@360nm; Noise Level: 100% ≤ 0.15% T; 0% ≤ 0.1% T; drift: ≤ 0.001A/h@500nm
Steps
1. One-click automatic correction of ABS value
2. Use the sample chamber to place the Cuvette for photometric testing
3. Connect computer or printer (optional) for data output or printing
4. Basis Weight test with software, such as standard Linear dispersion method or coefficient method
Notice
• The printer is an optional function and requires additional configuration
• The software function is optional and needs to be used together
• Use imported tungsten lamps, pay attention to the replacement cycle
• Ensure that the sample room is clean to avoid affecting the detection accuracy
