UltraChem® 40 Liquid Particle Counter

NanoVision Technology — The Visible Advantage Your products need reliable contamination monitoring. You need to detect the smallest particle possible. Now get both — sensitivity to 40 nm particles with the greatest reliability available on the market. If your application requires measuring small particles in chemicals with high molecular scatter, UltraChem 40 is the best tool for the job. NanoVision Technology eliminates the competition between the light scattered by fluid molecules and that from the particles. This makes 40 nm sizing possible for the first time. Background and false counts are a thing of the past. The NanoVision Technology breakthrough ensures only information that matches a particle fingerprint is counted. The result: Data you can act on with confidence. UltraChem 40 Liquid Particle Counter achieves this sensitivity in chemicals using a low cost laser diode. The proven long life of the diode enables a three-year warranty for maximum confidence in your particle counter. Finally the performance you demand from a particle counter you can trust — UltraChem 40.
