Particle Counters

Environmental particle counters provide a critical complement to traditional mass-based air quality measurements. While mass-based methods capture the total weight of airborne particles, number-based techniques - like those used in Condensation Particle Counters (CPCs) - offer a more advanced approach by counting individual particles, regardless of size. This is especially important for ultrafine particles, which contribute little to overall mass but may exist in large quantities from sources like traffic and residential heating. CPCs detect particles above a defined cutpoint (commonly 2.5, 7, or 10 nm) and count nearly all particles across the ultrafine and fine ranges. TSI offers a wide range of CPC models trusted for urban and remote environmental monitoring. Whether you're looking for a low-maintenance, water-based instrument like the 3783 Environmental Particle Counter, or require full compliance with EN 16976 using our 3750-CEN model, TSI’s CPCs deliver reliable, real-time particle number concentration data around the world.

Why Choose Environmental Particle Counters

Environmental particle counters quantify the number of airborne particles in real time, often across distinct size channels. This capability supports source identification, trend analysis, and exposure assessments for outdoor spaces ranging from neighborhoods and school campuses to industrial perimeters and construction zones. Unlike mass-only metrics, particle number data can highlight ultrafine and fine particle behavior, offering added context for traffic emissions, combustion sources, and regional haze.

Key Advantages

  • Real-Time Visibility: Understand changes minute by minute and compare hotspots across a network.
  • Size-Resolved Data: Access particle counts by size channels to support source attribution.
  • Rugged Design: Weather-resistant housings and field-ready components support long-term outdoor deployments.
  • Scalable Networks: Connect multiple counters to map air quality across a district, corridor, or campus.
  • Connected Data: Integrate with cloud platforms and APIs for dashboards, alerts, and analytics.
  • Flexible Power: Support for mains, battery backup, and solar configurations.

Common Use Cases

  • Community Air Monitoring: Compare street-side versus backyard levels and share insights with residents.
  • Wildfire and Smoke Episodes: Track smoke movement, intensity changes, and recovery.
  • Construction and Roadwork: Quantify project-related dust and optimize mitigation strategies.
  • Traffic and Transportation Studies: Evaluate rush hour patterns and intervention impact.
  • Campus, Park, and Venue Air Checks: Inform outdoor activities and operational decisions.
  • Research and Field Studies: Complement mass metrics with particle number measurements for deeper analysis.

What to Consider

  • Measurement Objectives: Decide whether you need number counts, size channels, or mass estimations.
  • Location Logistics: Confirm power availability, mounting height, and exposure to prevailing winds.
  • Data Integration: Plan how you will visualize, export, and share data with stakeholders.
  • Maintenance: Schedule periodic optical checks, zero checks as applicable, and filter changes for inlets.
  • Siting Best Practices: Follow recognized siting principles to reduce bias and improve comparability.

Getting Started

  • Define goals, target size ranges, and data cadence.
  • Map potential sites and confirm connectivity and power.
  • Plan a pilot deployment to verify siting and data quality.
  • Expand to a network once workflows are established.

A well-planned particle counting program can elevate outdoor air insights for municipalities, research teams, and community groups. When combined with meteorological and gaseous pollutant data, the results can inform targeted interventions and measure progress over time.
