Let’s face facts; manual monitoring of cleanroom particulate counts is costly, monotonous and highly error prone. Cleanroom managers are very aware that by far the greatest contamination threats come from individuals entering controlled spaces. Understandably, to reduce the number people accessing these critical environments, many companies are tasking the cleanroom operations staff already working within these spaces with the additional responsibility for manual environmental monitoring (EM).While this approach has obvious benefits, such as lower labor costs and reduced contamination risks, it also introduces significant new data integrity issues.

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.

Cleanrooms are specially constructed, highly regulated environments for controlling atmospheric conditions and eliminating dust particles. As such, these spaces require continuous monitoring of many environmental parameters. Without this continuous monitoring, the quality of manufactured product and safety of cleanroom personnel could be at risk.
