Environmental Particle Counters

Environmental particle counters reveal that while sources like traffic and heating contribute high numbers of fine particles, they add little to particulate mass. Increasingly, monitoring networks use Condensation Particle Counters (CPCs) to supplement gravimetric PM measurements with real-time particle number concentrations. TSI’s environmental particle counters deliver accurate, reliable particle measurements worldwide. The water-based 3783 Environmental Particle Counter runs continuously for up to four weeks, ideal for remote monitoring stations. For strict data comparability requirements, the 3750-CEN butanol-based CPC meets the EN 16976 European standard.

Environmental particle counters provide the continuous data streams that modern air quality and exposure studies require. By measuring particle number, mass proxies, or size fractions, these instruments help researchers characterize spatial and temporal variability, identify sources, and assess interventions. Systems are designed for long-term deployments with features that support reliability, data continuity, and efficient fleet management.

What sets them apart:

  • Continuous operation: Stable performance for long campaigns with minimal intervention.
  • Network-ready: Cellular, Wi-Fi, or Ethernet connectivity enables real-time dashboards and centralized data management.
  • Scalable architecture: From single sites to campus-wide or city-scale networks, deploy sensors and counters that grow with your program.
  • Integration: Pair with meteorological sensors and gas analyzers to build multi-parameter datasets for source apportionment and modeling.

Applications:

  • Urban air quality mapping and community exposure assessments.
  • Indoor environment studies in schools, offices, and healthcare settings.
  • Industrial fence-line monitoring and research-grade screening.
  • Intervention evaluation, such as filtration upgrades or policy impacts.
  • Method development supporting academic publications and collaborative consortia.

Operational considerations:

  • Choose instruments with size bins and measurement principles that match your study objectives.
  • Plan for power and enclosure requirements in harsh weather or remote locations.
  • Implement automated QA checks and data validation routines to help maintain data integrity.
  • Use APIs and standardized formats to streamline analysis and publication.

By combining continuous measurement, robust communications, and flexible deployment options, environmental particle counters help research teams generate credible datasets, accelerate discovery, and communicate findings to stakeholders with clarity.
