Current industry filter leak scan testing standards and recommended practices require a minimum of 10 micrograms per liter (ug/l) as an upstream aerosol challenge concentration when using photometry as the primary detection method. While higher concentrations may be used, 10-ug/l is the minimum required concentration that must be used to maintain compliance. ATI aerosol photometers are designed to operate in accordance with all current industry standards and recommended practices.
Required Upstream Aerosol Concentration

Hello,
The minimum required concentration that must be used to maintain compliance according current ISO 14644-3 is not more 10 ug/l, but 1 ug/l. Photometer TDA 2i is not able to establish its upstream concentration for such a low concentration.
Is there something planned or considered to technically adapt this possibility ?
Thanks & Regards
