Smart Upstream Sampling and Downstream Filter Scanning System. Incorporating an ergonomic lightweight-scanning probe with touchscreen user interface, the ScanAir Pro System also includes a SOLAIR portable particle counter and a dual-port diluter that can be remotely switched between measurements from the touch screen handle. The ScanAir Pro System allows you to take an upstream and downstream measurement that displays real time percent leak information on the integrated touch screen display.
