1. Product Introduction of HZSY-7 Portable Infrared Oil Meter

HZSY-7 Portable Infrared Oil Measuring Instrument is aimed at the measurement and detection of petroleum, animal and vegetable oil content in groundwater, surface water, domestic sewage and industrial wastewater, and the concentration of cooking fume in the catering industry. Use carbon tetrachloride to extract oily substances in water, determine the total extract, then absorb the extract with magnesium silicate, and measure petroleum after removing polar substances such as animal and vegetable oils. The content of total extracts and oils are determined by the wave numbers of 2930cm-1 (stretch vibration of C-H bond in CH2 group), 2960cm-1 (stretch vibration of C-H bond in CH3 group) and 3030cm-1 (stretch vibration of C-H bond in aromatic ring) respectively. C-H bond stretching vibration) absorbance A2930, A2960 and A3030 band at the calculation. The content of animal and vegetable oils is calculated as the difference between the total extract and the petroleum content. Promulgated the "Water Quality Determination of Petroleum and Animal and Vegetable Oils Infrared Spectrophotometry" (HJ 637-2018) standard. "Determination of stationary pollution source exhaust gas oil fume and oil mist - Infrared spectrophotometry HJ 1077-2019" standard.

3. Product Features of HZSY-7 Portable Infrared Oil Meter

1. The real infrared spectroscopic three-wavenumber oil measuring instrument can comprehensively investigate the stretching vibration of the C-H bond in the CH2 group in the oil (measured by 2930cm-1), and the stretching vibration of the C-H bond in the CH3 group (measured by 2960cm-1) And the stretching vibration of the C-H bond in the aromatic ring (measured by 3030cm-1), the measurement result is not affected by the change of the oil composition.

2. There is no need to make a standard curve, no need to adjust the zero point, no full adjustment, no need to calibrate, and the sample can be directly measured. The instrument can be used for on-site measurement on occasions, which is convenient, fast, and directly prints the data report.

3. One cuvette can be used, which eliminates the influence of the difference between cuvettes on the measurement results, and the measurement accuracy is higher. When multiple cuvettes are used, there is a cuvette database with the ability to save cuvettes Data, the function of automatically subtracting the background of the cuvette. Customers can adjust the curve according to their actual situation to complete the measurement in different occasions.

4. Imported long-life light source, no need to replace the light source.

5. Modulated light source, high signal frequency, frequency selective amplification, signal output is not affected by stray light.

6. The grating is controlled by a precision stepping motor, with automatic wavelength correction function, high wavelength accuracy and good repeatability.

7. The use of semiconductor detectors has a long service life, and the application of semiconductor refrigeration technology makes the signal output more stable, and the signal output is not affected by room temperature changes.

8. Powerful functions: It has multiple functions such as infrared spectrophotometry, non-dispersive infrared photometry, and spectral scanning. It has a wide scanning range and can be used as an infrared spectrometer.

9. HZSY-7 direct-reading infrared spectrophotometric oil measuring instrument | portable oil measuring instrument has an automatic light source compensation system and a signal drift correction system, and the baseline has no drift.

10. Built-in single-chip microcomputer control, liquid crystal display, can work independently without the computer. It can also be connected to the computer to control the host through the USB interface, with perfect functions and easy operation. the

11. On the same desktop, the spectrogram, measurement steps, and measurement results are simultaneously displayed, and the wavenumber position, absorbance and transmittance of any point in the spectrum can be read out in the spectrogram. the

12. The spectrogram, measurement conditions, and measurement results can be saved in computer files or directly printed out. the

13. Fast detection speed: infrared spectrophotometry 25 seconds/time, non-dispersive infrared photometry 2 seconds/time.
