UltraChem® 100

Sensitivity range: 100 – 500 nm

The UltraChem® 100 Liquid Particle Counter gives you reliable contamination monitoring with the ability to detect the smallest particle possible.

If your application requires measuring small particles in chemicals with high molecular scatter, the UltraChem Liquid 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.

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. The UltraChem 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.

Get the performance you demand from a particle counter you can trust.
