●Beautiful and elegant appearance, using ABS engineering plastic casing, resistant to acid and alkali corrosion.

●Adopting high-throughput optical system, integrated optical path design, short optical path length, high energy, small instrument size, light weight, first splitting and then absorbing, meeting the requirements of infrared spectroscopy characteristics, good stability, and high signal-to-noise ratio; Using a precision stepper motor to control the grating, it has wavelength correction function, high wavelength accuracy, and good repeatability;*The design of the colorimetric pool structure is suitable for0.5Any colorimetric dish up to 5 centimeters.

●By using electrically modulated light sources, the heating intensity of the light source is reduced, which is beneficial for system heat dissipation. The lifespan of the light source can reach over 8000 hours. At the same time, due to the absence of mechanical cutting motion components, the instrument structure is simplified and the stability of the instrument is improved.

●Using a mechanical and optical dual calibration system for automatic positioning and wavelength measurement, appropriate concentration oil standard samples are used to automatically calibrate the wavenumbers at 2930cm-1, 2960cm-1, and 3030cm-1, eliminating the influence of human factors and accurately measuring absorbance. ZUI greatly increases instrument stability.

The analysis software automatically determines whether the purity of the tetrachloroethylene reagent is qualified or unqualified.

●Instrument measurement method: The instrument has been newly developed and uses calibration coefficients for direct measurement, which complies with three different national standards: water quality, fixed pollution source exhaust gas, and soil. There is no need to add any proportional coefficients to correct the final value, and no need to create additional standard curves. The final result can be obtained by direct measurement.

●Instrument calibration method: In addition to directly measuring the calibration coefficient, the instrument is also compatible with the function of producing standard curve measurement data. Customers can choose the appropriate calibration and measurement method according to their needs.

●Capable of measuring calibration coefficients: According to HJ638-2018 national standard 8.1, the instrument calibration coefficients X, Y, Z, and F can be calculated using standard solutions of n-hexadecane, isooctane, and benzene.
