Particle Counters and Detectors

TSI’s particle counters and detectors are optimized for diverse applications, from environmental research to sensitive environments and beyond. In environmental research and monitoring, users encounter high particle concentrations in city centers, near highways, or ports, as well as very low concentrations in remote reference sampling locations. In laboratory settings, particle counters are often paired with sizers to measure size distributions. For workplaces, hospitals, schools, and residential spaces, water-based Condensation Particle Counters (CPCs) ensure occupant safety and health. Combustion aerosol presents unique challenges, such as sampling without altering particles or meeting regulatory directives for engine exhaust. For calibration purposes, reference counting is supported by Aerosol Electrometers. Whatever your challenge, TSI offers a solution—let us help find yours.

Particle counters and detectors serve as the backbone of aerosol science and many adjacent fields, providing the resolution and repeatability researchers require to explore particle behavior with confidence. Whether you are investigating particle formation, validating cleanroom processes, testing filtration efficiency, or studying combustion, this category spans instruments that help you quantify what matters: number concentration, size distribution, and time-resolved dynamics.

Core capabilities include single-particle sensitivity, a wide dynamic range to handle both low and high concentrations, and size coverage from a few nanometers to tens of micrometers when paired with complementary techniques. Options range from condensation particle counters for nanoparticle counting to optical and aerodynamic methods for sizing larger particles, plus electrometers and classifiers that enable advanced measurement schemes.

  • Measurement versatility: Characterize aerosols across nano to micro scales with modular systems.
  • Repeatable methods: Calibrations traceable to recognized standards help support consistent, comparable results.
  • Data you can act on: Real-time outputs, onboard storage, and connectivity streamline experiments and analysis.
  • Integrated workflows: Interfaces with classifiers, generators, diluters, and deposition tools help accelerate study design.

Common applications:

  • Filtration and media testing for performance benchmarking.
  • Cleanroom and process studies where particle levels affect outcomes.
  • Engine, combustion, and alternative-fuel research targeting particle behavior.
  • Environmental and indoor air research requiring continuous monitoring.
  • Materials and nanotechnology where particle size and concentration influence function.

Selection tips:

  • Define the size range and concentration levels relevant to your work.
  • Consider time resolution needs for dynamic processes.
  • Plan for integration with classifiers, diluters, or samplers.
  • Evaluate data interfaces and software for analysis and collaboration.

Designed for R&D environments, these instruments help teams accelerate experimentation, compare results across sites, and translate findings into actionable insights that advance innovation.
