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.
