Applications of Compressed Air Oil Content Analyzer

Used for oil content analysis in compressed gases across industries such as aerospace, medical, special equipment, air separation plants, universities, etc. Different industries have varying quality requirements for compressed gases, and oil content is one of the factors affecting compressed gas quality. It can also be applied to measure oil content in surface water, groundwater, industrial wastewater, as well as monitoring oil in flue gas from the catering industry and oil content in solids. This instrument is a professional device for measuring oil content in water, gas, and solids.

Basic Principle

When monochromatic light passes through the measured solution, its energy is absorbed. The intensity of light absorption is proportional to the concentration of the substance being measured, in accordance with Lambert-Beer's Law: A=log(1/T)=log(I0/I)=a×b×c.
