Traditional Laskin nozzle and thermal aerosol generators are designed for use with photometers which commonly require 10µg/liter or greater of an aerosol challenge for leak testing/sizing. Concentrations of 10µg/liter are on the order of 100x greater than what is optimal for leak testing/sizing with a particle counter.

The new Lighthouse ScanAir Pro System is a particle counter based HEPA/ULPA filter scanning system. It is the only easy and lightweight method for testing PTFE HEPA filters. Use it to scan filter media for leaks.
