Infrared oil tester

Instrument Introduction

The HD-HC820 infrared oil meter is developed and manufactured according to China's environmental protection standards. The instrument is a special infrared spectrometer for detecting the oil content in water, gas, and solids. It can be used to detect the oil content in surface water, groundwater, and industrial wastewater, as well as for the detection of oil in the flue gas of the catering industry and the detection of petroleum in the soil.

Application Field

The 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.

Comply with the standard

"HJ637-2018 Infrared spectrophotometry for the determination of petroleum and animal and vegetable oils in water";

"HJ1077-2019 Infrared spectrophotometry for the determination of oil smoke and oil mist from waste gas from fixed pollution sources";

"HJ1051-2019 Infrared spectrophotometry for the determination of petroleum in soil";

Functional features

1. Comply with the national standard HJ637-2018. The infrared three-wave number spectrum is clear and the scale is accurate. It can clearly display the absorption spectrum and absorbance generated by the three wave numbers;

2. The instrument can be calibrated with both standard curves and correction coefficients. Multiple calibration methods meet the requirements of different use environments. Users can also establish standard curves by themselves;

3. Baseline stability: The zero point is automatically adjusted in real time (eliminating the influence of baseline drift). The computer collects light The instrument collects the signal when the light source is on and the signal when the light source is off, realizing real-time automatic adjustment of the zero point, thereby simplifying the operation and improving the long-term stability of the signal;

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

5. The instrument uses a thermal release photoelectric detector to collect dual signals when the light source is on and off, realizing real-time automatic adjustment of the zero point of infrared light;

6. The detachable integrated optical system has a small size, short optical path, high energy, first splitting and then absorbing, and good stability;

7. Equipped with Holder Electronics special analysis software, integrating spectrum, scanning, analysis, and calculation;

8. The software is equipped with a project detection project selection function, which can select oil determination in water and oil fume determination in the catering industry , oil determination in solid soil;

9. With automatic statistical analysis, spectrum display, storage, printing and other functions;

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

11. Scanning spectrum, custom scanning mode can be customized, fast or precise;
