4Technical characteristics of UV spectrophotometer oil analyzer
1. The true three wavenumber and infrared three wavenumber spectra are clear and accurately calibrated, and can clearly display the absorption spectra and absorbance generated by the three wavenumbers;
2. It has the function of measuring instrument calibration coefficient;
3. Able to test the transmittance and purity of the extractant, and distinguish interfering substances;
4. The NC infrared light source used has a long lifespan and no other light exposure;
5. Electric modulation light source, replacing mechanical switching light source, simplifies structure, and has good performance;
6. The thermal sensitive photodetector collects dual signals when the light source is on or off, achieving automatic adjustment of the zero point of infrared light at any 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 extractants;
9. It has functions such as automatic statistical analysis, spectrum display, storage, and printing.
10. A detachable integrated optical system with small size, short optical path length, and high energy. It separates light before absorbing, and has good stability.
