The AcuPro® is an industrial strength analyzer with a complete sampling system, heated optical cell, and integrated controller for continuous measurement of flammable, and some combustible vapors, from 0% to 100% of the Lower Flammable Limit (%LFL, or LEL). It is suitable for monitoring a single solvent in a wide variety of processes. And it may be used for mixtures of solvents with a reduced level of accuracy in processes where the normal solvent concentrations are below 25%LFL.
