Particle Measuring Systems is the largest particle counter manufacturer in the world. How did they accomplish this? Simple – they invented laser particle counters – a system that provides accurate data and results for clean room environments. They sets the standard for contamination monitoring in semiconductor, data storage, display, pharmaceutical, nanomaterial, aerospace, and related industrial manufacturing applications. Particle Measuring Systems has registered more than 60 patents and actively remain up to date with industry, trade, and technology changes. These innovations have enabled companies to make fact-based decisions, improve process yield, and comply with changing regulatory requirements.
