CHF-1100 infrared spectrophotometer Introduction
CHF-1100 infrared spectrophotometer is mainly used for the measurement of oil content in surface water, groundwater and industrial wastewater. It can also be used for monitoring the oil in the flue gas of the catering industry and monitoring the oil content in the solid. The instrument is a professional instrument for measuring the oil content in water, gas and solids. Features
1. The true three-wavenumber, the infrared three-wavenumber spectrum is clear, the scale is accurate, and the absorption spectrum and absorbance generated by the three wave numbers can be clearly displayed;
2. With the function of measuring instrument correction coefficient;
3. It can test the light transmittance and purity of the extractant, and can distinguish various interferences;
4. Using a dedicated NC infrared light source, long life, Wu other light;
5. Electrically modulating the light source instead of mechanically switching the light source, simplifying the structure and improving performance;
6. The heat release sensitive photodetector collects the double signal when the light source is turned off, and realizes the automatic adjustment of the zero point of the infrared light from time to time;
7. Controlled by Windows XP or win7 operating system;
8. Other non-hydrocarbon organic solvents such as tetrachloroethylene and trichlorotrifluoroethane can be used as the extracting agent;
9. With automatic statistical analysis, spectrum display, storage, printing and other functions.
10. Removable integrated optical system, small size, short optical path, high energy, first absorbed after light splitting, good stability. Technical parameters
