SR-IF637 Infrared Oil Content Analyzer

This infrared oil content measuring instrument adopts infrared spectrophotometry to scan the sample for monochromatic spectrum. It can display and print the wave position of the sample spectrum and absorption peak, and can measure the oil concentration in the sample. It is applied for the determination of surface water, groundwater, domestic sewage, industrial wastewater, petroleum in the soil and animal and vegetable oil content. And it is widely applied in environmental monitoring systems, petrochemicals, sewage treatment plants, thermal power plants, steel enterprises, scientific research and teaching in universities, agricultural environment, automobile manufacturing, catering industry, soot emission measurement, marine environmental monitoring, environmental research, etc. It meets with national standards: "HJ637-2018 Water quality Determination of petroleum and animal and vegetable oils by infrared spectrophotometry".
