Met One Instruments Manufacturing Products

monitor facility functions and process controls

In certain manufacturing processes, reducing the number of airborne particles is critical. Yields drop dramatically when components and processes interact with dust, airborne microbes, aerosol particles, and trace moisture. To minimize defects and ensure consistent quality, Met One Instruments offers a range of portable and small footprint particle counters and mass monitors. These devices are used to monitor facility functions and process controls. They are often an essential element of manufacturing quality assurance and control programs. Our models meet ISO 14644-1:2015 criteria and can be used in Class 3 through Class 9 cleanrooms. Certain models also meet the requirements for the Manufacture of Sterile Medicinal Products per EU GMP Annex I (EMEA) by meeting Grade A through D size and count requirements.
