Fully automatic infrared oil tester

Product Overview

The HD-QH900 fully automatic infrared oil meter is developed and manufactured according to China's environmental protection standards. The fully automatic infrared oil meter is a dedicated fully automatic infrared spectrometer for detecting the oil content in water. The extractant is automatically injected into the water sample, and the oil in the water is extracted into the reagent through automatic extraction. The water and the reagent are separated by a separation device with technology, and the animal and vegetable oils are adsorbed by magnesium silicate. According to the national standard requirements, petroleum and animal and vegetable oils are automatically measured and calculated at 3030, 2960, and 2930cm-1 respectively.

Application Fields

The fully automatic infrared oil meter can be widely used in water environment detection systems, sewage treatment plants, water companies, petrochemicals, university research institutes, hydrology and water conservancy, metallurgy and steel, biomedicine, agricultural environment monitoring, marine environment monitoring, wool spinning and dyeing, papermaking and other fields of water quality detection.

Functional features

1. In accordance with the Chinese environmental protection standard "HJ637-2018", the infrared three-wave number spectrum is clear and the scale is accurate, which can clearly display the absorption spectrum and absorbance generated by the three wave numbers;

2. Automatic sampling, extraction, water removal and filtration, magnesium silicate adsorption, measurement, drainage, cleaning, 6-12 samples can be made continuously to achieve automatic detection;

3. The extractant is fully enclosed in all links such as liquid storage, sample extraction, testing and waste discharge, reducing the chance of operators contacting harmful reagents, which is safer;

4. Real-time monitoring of reagent residue, insufficient reagent volume, can provide early warning function;

5. The oil-water separation membrane is used instead of anhydrous sodium sulfate to absorb trace water, eliminating the step of frequent replacement of anhydrous sodium sulfate, which is more convenient to use and easy to maintain;

6. The instrument has a self-designed magnesium silicate addition technology that not only meets the national standard requirements, but also avoids the occurrence of easy blockage failures;

7. The instrument adopts a special downward pressure stirring extraction technology, which has higher extraction efficiency;

8. The instrument adopts Win7 operating system, built-in Holder Electronics special analysis software, special analysis Software, integrating spectrum, scanning, analysis and calculation;

9. The instrument has a built-in 8-inch touch tablet computer and an external wireless mouse and keyboard for operation, which is simple, convenient and fast;

10. The instrument can be calibrated with standard curves or coefficients, and a variety of calibration methods can meet the requirements of different use environments;

11. The dilution and enrichment ratios can be set arbitrarily;

12. Each concentration point of the curve can be prepared to automatically generate a standard curve;

13. Light source system: The service life of the light source can reach more than 10,000 hours. The light source uses electrical modulation and light source technology to prevent the internal temperature of the instrument from being too high and affecting stability;

14. Automatic wavelength correction, the wavelength can be adjusted arbitrarily within the specified range; qualitative and quantitative analysis of all substances with characteristic absorption within the range;

15. It has automatic statistical analysis, spectrum scanning display, storage, printing and other functions;

16. The instrument has 30G storage space and can store 1 billion sets of historical data;

17. Quick data query can be performed by time, sampling location, and sampling personnel, and the detection data can be printed;

18. The entire pre-treatment system adopts full protection The material is non-corrosive and non-oil-philic, and the air self-cleaning cleaning process can minimize the cross-influence of high and low concentration water samples;

19. The front end of the instrument adopts a molecular sieve structure to prevent impurities from clogging the pipeline;

20. The sampling bottle is a sample bottle with a scale display, which can directly and accurately measure and collect water samples. There is no need to transfer water samples, and it can be directly tested on the machine;

21. The tested water samples and solvents are automatically discharged into the waste liquid barrel by blowing, and there is no residue in the pipeline, which does not affect the test of the next sample;

22. The instrument has self Automatic dilution function can identify unknown high-concentration samples and automatically dilute according to the set over-concentration threshold;

23. The instrument is equipped with a mobile phone APP, which can realize the control of the instrument operation status, fault warning, data approval query, and remote diagnosis functions through the big data cloud;
