Fidas® 200 S

EN 16450 approved fine dust aerosol spectrometer for simultaneous measurement of PM2.5 and PM10 in weatherproof cabinet for outdoor installation

The Fidas® 200 S version is a 19" plug-in unit mounted in a splash-proof stainless steel control cabinet for outdoor use (temperature range -20 - 50 °C). A larger, air-conditioned control cabinet is available on request, allowing the installation of additional devices. Variants of the Fidas® 200 S are the basic Fidas® 200 and the Fidas® 200 E with a remote sensor (for easier integration into stations with existing roof feed-through).
