All filter test equipment from TSI, used for testing efficiencies of filter media and a variety of air filters, including high and very high-efficiency filters, respiratory filters, cartridges, and protective garments, is known for its simple and reliable operation.

All of our filter testers can determine the efficiency of filters using submicron poly- and monodisperse oil and/or sodium chloride aerosol. Additionally, TSI's filter test solutions are used to comply with various testing standards and regulations around the globe.

Aerosol neutralizers are an essential piece of many aerosol research studies because aerosol particles dispersed by nebulization, combustion, or powder dispersion are usually electrostatically charged.

Normally, a high level of electrical charge is undesirable because it increases the particle loss to the walls of transport and sampling systems, or it can affect filter-efficiency measurements.

To ensure that instruments operating on the electrical mobility principle work properly, aerosol particles entering these instruments require an aerosol neutralizer to impart a predictable charge distribution to the aerosol particles.

Neutralizers can be separated into two categories based on how they charge the particles. One group is the radioactive neutralizers, which use the emission of alpha (positive) or beta (negative) particles from decaying radioactive elements to impart charge to the particles. The other group is the non-radioactive neutralizers, which use electricity to generate x-rays or produce high voltages that can charge the particles directly.
