Particle Counter Experts

Experts in Particle Counting Contamination Monitoring Solutions Since 1972 with presence around the globe

Superior Particle Counting Knowledge

Particle Measuring Systems (PMS) is the inventor of laser based-particle counting, and we continue to lead the field with our dedication to hiring and training industry professionals. Our experts are recognized as thought leaders, evidenced through our speaking requests, webinars, authored papers and high education levels.

Our technology experts actively participate with customers and industry standards committees to understand the evolving needs and challenges faced by our broad customer base. Our renowned Particle College® program includes a two-day series of lectures and hands-on labs covering basic particle measuring concepts to advanced applications of contamination monitoring and control.

Superior Particle Counting Technology

A core investment in research, engineering and product manufacturing has resulted in more than 60 patents related to our products and applications. We create the technology that enables you to make fact-based decisions, improve yield process, and comply with changing regulatory requirements such as Annex 1, ISO 14644-1, USP 788, USP 797, 21CFR Part 11, and more. Our technology can measure particle sizes as small as 20 nm in water and chemicals, 10 um in air, and molecular contamination concentrations in parts per trillion. We are also leaders in microbial monitoring developing traditional techniques that reduce false positives.

Superior Particle Counter Quality

Particle Measuring Systems sets the standard for contamination monitoring by first designing reliability into our particle counters and then backing the technology with an unmatched Quality Management System.

Superior Service

Our service technicians are well trained to calibrate your instruments to the highest standards, and our software-controlled approach automates critical steps that drive consistency in each calibration. This ensures the same calibration results and performance, consistent with factory calibration, regardless of where the calibration is performed- anywhere in the world.

All calibrations are completed in strict accordance with ISO guidelines. PMS provides an unequaled counting efficiency test for first-channel sensitivity. For pharmaceutical applications, particle counters must be calibrated to the exacting standard of ISO 21501-4:2007, which includes measurements to verify and set flow rate, counting efficiency, particle sizing, resolution, signal ratios and zero count. Each calibration is also completed using NIST-traceable standards, and a certificate is provided with each calibration
