The UltraChem® 40 Chemical Particle Counter from Particle Measuring Systems gives you reliable liquid particle monitoring with the ability to detect 40 nm particles. This liquid particle monitoring solution is part of Particle Measuring Systems’ (PMS) complete line of particle counters for air, water, and chemical particle monitoring.

If your application requires monitoring small particles in chemicals with high molecular scatter, the UltraChem Chemical Particle Counter 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. This results in data you can act on with confidence. Ultra Chem is also available in 100 nm model.

The UltraChem Chemical 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 (one-year warranty on electronic flow controller) for maximum confidence in your particle counter.
