Setra’s wide array of non-viable particle counters are used throughout critical environments to measure particle concentrations of various sizes; these counters use a long-life laser diode, light scattering, and photo detector to calculate particle size and quantities as the sampled air passes through. Particle counters are required for cleanroom certification but are also often used for continuous, sequential, or periodic monitoring of the space between certifications and to ensure that particle levels are maintained below critical thresholds during manufacturing. This post will look at Setra’s different particle counters and their differences to help you decide upon the correct unit(s) for your application.
