4Technical features

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. Capable of measuring instrument calibration coefficient function;

3. Can test the transmittance and purity of extractants, and distinguish various interferences;

4. adoptedNCInfrared light source, long lifespan, can be illuminated by other types of light;

5. Electric modulation light source, replacing mechanical switching light source, simplifies structure, and improves 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. adoptWindows XPorwin7Operating system control;

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. Detachable integrated optical system, small size, short optical path, high energy, first splitting and then absorbing, good stability.
