Aerosol Photometers

Aerosol Photometers

Aerosol photometers are devices used for testing and evaluating the performance of filters, particularly those used in air filtration systems. These photometers measure the upstream and downstream concentration of airborne particles, allowing for the assessment of filter efficiency and performance.

Alpha Scientific offers a range of high performance aerosol photometers, aerosol generators and related accessories for testing HEPA filters in cleanrooms and controlled environments to the latest AS 1807:2021 and ISO 14644-3:2021 standards. Aerosol photometers are also widely used in testing H class vacuum cleaners, in the asbestos, silica and related industries and in various other markets.

Aerosol photometers are commonly used by testing and certification companies, HEPA filter manufacturers, cleanroom operators and many other organizations. They may be used with or without aerosol generators to make accurate and reliable measurements. Particle counters, ventilation test intruments and other equipment sold by Alpha Scientific is also commonly used by many of these organizations.
