liquid concentration meter

PR-3S inline concentration meter1. Product overviewMeasurement principle uses refraction of light to determine real-time liquid concentration and displays digitally; provides analog output (or communication output) for control.When light enters the prism in contact with flowing solution, part of light refracts into the solution and is absorbed, while the rest reflects; beyond a certain incident angle total reflection occurs.The angle at which total reflection begins is called the critical angle; the reflected light is measured by a CCD camera and converted to concentration based on refractive index.Concentration and refractive index have a mathematical relationship depending on the liquid; convert to concentration accordingly.No auxiliary reagents are required on site; measurable liquids include: DMAC,NMP,DMF, glycol ethers, diesel, emulsion, ethylene glycol, caustic soda, ammonia, sodium hydroxide, alcohol cleaners and more; direct measurement of various chemical concentrations is possible.PR-3S online liquid concentration and refractive index analyzer supports various installation methods; compact sensor, unaffected by liquid fluctuations; long-term stability and measurement reliability; no frequent recalibration needed.Automatic temperature compensation is built in; measurement at different temperatures is possible.Optional multi-point curve concentration measurement; can be used for various liquids.3.
