What Particle Measuring Systems does
Particle Measuring Systems (PMS), founded in 1972 and headquartered in Boulder, Colorado, is a private instrumentation and advisory company specializing in contamination control for pharmaceutical cleanrooms. Its product portfolio centers on two complementary technology lines: nonviable particle counters that perform continuous remote monitoring throughout critical aseptic processes, and viable monitoring systems based on active air sampling and passive settle plates for detecting microbial contamination. The company's instruments are deployed inside validated sterile manufacturing environments where regulatory submissions depend on documented monitoring data.
Beyond instruments, PMS has built a service business around regulatory expertise, most notably advisory engagements that help pharmaceutical manufacturers develop Contamination Control Strategies (CCS) compliant with EU GMP Annex 1 (2022). Service offerings extend to aseptic gowning compliance, risk-based sampling point determination, and product placement recommendations for cleanroom monitoring equipment. The go-to-market is primarily direct sales to sterile pharmaceutical manufacturers, with technical content and regulatory guidance as the main marketing channel; pricing is not publicly disclosed. The 2016 acquisition of CAS Clean-Air-Service signals an inorganic growth lever that has been used to broaden cleanroom service capabilities.
Revenue mechanics, ownership structure (whether independent, PE-backed, or subsidiary), customer logos, and geographic split are not disclosed in the available source material, which limits visibility into commercial scale despite the company's 501-1000 employee footprint and 50+ year operating history. John Mitchell serves as Chief Executive Officer and President.

Particle Measuring Systems competitors and assessment
Company assessmentDirect peers
- TSI Incorporated: TSI is a long-standing direct competitor in particle counters and air measurement instruments, including cleanroom monitoring applications. It is highly comparable in product category (aerosol and particle instrumentation) and shares pharmaceutical and life science end markets.
- Lighthouse Worldwide Solutions: Lighthouse is a direct competitor specializing in particle counters and cleanroom monitoring solutions for pharmaceutical and semiconductor customers. The overlap in viable/nonviable monitoring offerings and pharma GMP focus makes it one of the closest comparable companies.
- Climet Instruments Company: Climet manufactures airborne particle counters used in pharmaceutical, semiconductor, and industrial cleanroom environments. It is a direct peer with overlapping product lines and the same core customer use cases for contamination monitoring.
- Rion Co., Ltd. Rion is a Japanese manufacturer of particle counters and environmental measurement instruments with a strong installed base in Asian pharmaceutical and electronics cleanrooms. It competes head-to-head with Particle Measuring Systems on core particle counter technology and pharma end markets.
Emerging players
- BioVigilant (Azbil Corporation): BioVigilant, part of Azbil, pioneered rapid/immediate microbial detection for pharmaceutical cleanrooms using optical technologies. It overlaps with the viable monitoring side of Particle Measuring Systems' offering and represents a faster, technology-disruptive alternative.
- Veltek Associates, Inc. Veltek specializes in sterile cleanroom supplies including disinfectants, sterile wipers, and associated environmental monitoring consumables. It is comparable on the consumables side of contamination control and serves the same sterile pharmaceutical manufacturing customers.
Broad incumbents
- Beckman Coulter Life Sciences: As a Danaher-owned life sciences instrumentation brand, Beckman Coulter offers broader analytical and bioprocess instruments with overlap into particle and cell analysis workflows. It is a broader incumbent that can compete in pharma QC environments with a wider portfolio.
- MilliporeSigma: MilliporeSigma is the life science arm of Merck KGaA and supplies bioprocessing, filtration, and cleanroom contamination control products. It overlaps with the consumables and environmental monitoring side of the portfolio and sells into the same pharmaceutical QA/QC buyer.
- Sartorius AG: Sartorius is a major bioprocess and lab instruments supplier to pharmaceutical manufacturers. While it does not specialize in cleanroom particle counters, its broader quality and bioprocess portfolio competes for the same pharma QA/QC wallet and can bundle adjacent solutions.
- Hach (Danaher): Hach, a Danaher company, provides water and air quality analytical instrumentation with overlap into process and environmental monitoring instrumentation. It is a broader incumbent in industrial measurement that can leverage scale to compete in regulated monitoring applications.
