PCYY637 infrared photometric oil meter
Overview
1. Applicable standards: HJ637-2018
2. Uses: It is not only suitable for the monitoring of petroleum (mineral oil), animal and vegetable oil and total oil content in various water bodies and soils such as surface water, groundwater, sea water, domestic water and industrial wastewater, but also smoke (food industry soot) Instruments recommended by national standards for oil content monitoring.
3. Working principle: extract the oil in the water with carbon tetrachloride, tetrachloroethylene, S316, trichlorotrifluoroethane, freon, etc., and measure the total extract, then adsorb the extract with magnesium silicate. After the animals and other organisms such as vegetable oil, the petroleum is measured. The total extract and petroleum content were calculated by the absorbance at the bａnd of 3030 cm-1 2960 cm-1 2930 cm-1.
Features
The oil measuring instrument integrates optical, mechanical and electrical design, adopts aluminum alloy base, has good stability, large energy, long optical path and no drift. The unique circuit and optical path design make the signal-to-noise ratio significantly improved. A photoelectric signal that is submerged in noise.
The true three-wavenumber is in line with the national standard "HJ637-2012". The infrared spectrophotometry does not need to be a standard curve. It only makes a set of correction factors. It does not need to make a blank comparison and directly measures, reducing the workload of the operator and saving time.
Spectral scanning real-time tracking allows for a more intuitive view of the direction of the spectrum and the location of the scan.
By using double cuvette comparison, it is more effective to reduce the deviation of measurement results.
Real measurement, no false detection data.
Powerful, both quantitative and qualitative analysis, with a dedicated restaurant fume measurement menu, directly display soot measurement results.
The appearance of the instrument is beautiful and generous, and the operation is simple and easy to learn.
10.2-inch industrial-grade touch screen display, large screen, high definition, Chinese menu operation, display more content.
It can be used independently from the computer, or it can be connected to a computer to store, process, and transfer data.
The instrument comes with a printing function, which can print the measurement results in real time according to the users work needs, reducing the workload and error rate of the operator, and more convenient to meet the needs of different users.
