YJ-637E Fully Automatic Infrared Spectrophotometric Oil Content Analyzer
The basic principle of the fully automatic infrared spectrophotometric oil content analyzer is that when a monochromatic light passes through the tested solution, its energy will be absorbed. The degree of light intensity absorption is proportional to the concentration of the tested substance, conforming to the Lambert-Beer law: A=log(1/T)=log(I0/I)=a×b×c. It complies with national standards including: HJ 637-2018 "Water Quality - Determination of Petroleum and Animal and Vegetable Oils - Infrared Spectrophotometric Method", "GB3838-2002 Environmental Quality Standards for Surface Water", "GB18483-2001 Emission Standard for Cooking Fumes from Catering Industry", and "GB18918-2002 Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants". This instrument is mainly used for measuring the oil content in surface water, groundwater and industrial wastewater, and can also be applied to monitor oil in catering fumes and oil content in solids. It is a professional instrument for measuring oil content in water, gas and solids. It is also suitable for environmental monitoring systems of various departments, as well as testing laboratories of large and medium-sized enterprises in petrochemical, hydrology and water resources, water supply, wastewater treatment plants, thermal power plants, iron and steel enterprises, university scientific research and teaching, agricultural environmental monitoring, railway environmental monitoring, automobile manufacturing, marine environmental monitoring, traffic environmental monitoring, environmental scientific research and other fields.
