PARTICLE MEASURING SYSTEMS, INC

Particle Measuring Systems, Inc. specializes in the calibration and maintenance of high-precision aerosol and particle monitoring instrumentation, particularly for mission-critical environmental and industrial applications. Their core technical expertise lies in the calibration of laser-based particle counters such as the LASAIR II series, ensuring traceable accuracy in particle size distribution and concentration measurements. This work demands rigorous adherence to ISO 14644 and ANSI/ASHRAE standards, with deep proficiency in optical metrology, flow dynamics, and environmental chamber control. The contractor’s key differentiator is its focused capability in maintaining the integrity of airborne particle detection systems used in controlled environments, where even minor calibration drift can compromise data validity in sensitive operations. The company has demonstrated direct engagement with the Department of Defense, delivering calibration services for precision instrumentation used in defense-related environmental monitoring, cleanroom operations, or hazardous material detection. This relationship suggests alignment with DoD requirements for equipment reliability in field-deployable and facility-based monitoring systems, likely supporting aerospace, munitions, or biological defense programs. Their primary NAICS classification, 811210, reflects a niche specialization in the repair and calibration of electronic and precision equipment, positioning them as a technical services provider rather than a manufacturer. This vertical is critical in sectors requiring certified measurement integrity, including defense, pharmaceutical manufacturing, and semiconductor fabrication. Particle Measuring Systems, Inc. is a small business structured as a 2L entity, headquartered in Boulder, Colorado. While no federal certifications are currently listed, their work implies compliance with NIST-traceable calibration protocols and quality systems aligned with ANSI Z540. Their geographic presence and technical focus place them within the specialized supplier ecosystem serving federal agencies requiring validated environmental sensing systems.
