Particle Measuring Systems introduces the Surfex-300, a parts cleanliness testing station for large parts. Smaller parts can also be tested. The Surfex combines ultrasonic extraction, particle measurement, high-purity fluidics and automated software control to save time and increase throughput when testing the cleanliness of complex parts.The Surfex-300 decreases testing costs by reducing sample times to one-tenth of traditional manual methods, according to the company. Test recipes and simple menu-driven software eliminate data variability caused by human error. Highly reliable data with low sample-to-sample variation is ensured by establishing accurate particle baseline levels. Surfex is available with a variety of particle counter sensitivities and ultrasonic frequencies to provide parts cleanliness testing that is customized for specific applications.
