Aerosol photometers and generators are the critical instruments in ensuring cleanroom and HVAC compliance. Generators create a controlled cloud of airborne particles or liquid droplets of a specific, uniform size, while photometers detect them to spot invisible HEPA/ULPA filter leaks. Together, they protect sterile manufacturing and laboratory environments from costly contamination. Filter integrity testing is required once or twice a year, depending on the ISO class of the cleanroom. The use of portable photometers and aerosol generators are the industry standard for HEPA Filter testing.

Common Applications

• Cleanroom Validation: Ensures that manufacturing environments in pharmaceuticals, semiconductor fabrication, and aerospace remain completely free of contaminants.

• Biosafety Cabinets (BSCs): Certifies that laboratory hoods adequately protect operators from hazardous pathogens. 

• Hospital Environments: Confirms that isolation rooms and surgical suites meet strict air quality and containment standards.
