Particle Counters & Detectors

Particle Counters & Detectors

Our family of particle counters and particle detectors contain instruments optimized for a variety of applications.

In environmental research and monitoring, customers face high concentrations in city centers, near freeways or harbors, or very low concentrations in remote locations which are used as reference sampling points.

In the laboratory, particle counters are often combined with particle sizers to measure size distributions.

Workplaces, hospitals, schools, residential homes and other sensitive environments prefer water-based Condensation Particle Counters (CPCs) to ensure the occupants’ safety and health.

Combustion aerosol has its own challenges, such as sampling the aerosol without changing it, or following regulatory directives for engine exhaust.
For the purpose of calibration, reference counting is typically performed with an Aerosol Electrometer.

Whatever your challenge is, TSI offers a solution. Let us help you to find yours.

Filter Testers

Filter Testers

All filter test equipment from TSI, used for testing efficiencies of filter media and a variety of air filters, including high and very high-efficiency filters, respiratory filters, cartridges, and protective garments, is known for its simple and reliable operation.

All of our filter testers can determine the efficiency of filters using submicron poly- and monodisperse oil and/or sodium chloride aerosol. Additionally, TSI's filter test solutions are used to comply with various testing standards and regulations around the globe.
Heat Stress Monitors

Heat Stress Monitors

Heat stress management is often viewed as time-consuming and complex. Simplify your heat stress management with TSI’s intuitive QUESTemp° Series Heat Stress Monitors.

QUESTemp° Heat Stress Monitors are designed to quickly and accurately evaluate potential heat stress environments. These instruments deliver high-performance monitoring using Wet Bulb Globe Temperature (WBGT) sensing technology, the standard for heat stress management, and the calculation of a WBGT Index value.

Our monitors allow you to eliminate daily maintenance. Convenient stay time parameters per multiple standards help determine work-rest ratios, and IP 54 ingress rating helps protect units from exposure to dirt, dust, oil and water.

Our monitors are designed to withstand the rigors of everyday use in demanding environments, providing reliable monitoring throughout the life of the product.
