Maintenance-free AERASGARD® RPS - SD room air quality measuring transducer with active output, in an elegant plastic housing with snap-on cover, base with 4-hole attachment, for detecting the particulate matter (PM) content (0...500 g/m3).

The transmitter converts the measurand into a standard signal of 0-10 V (fixed).

Maintenance-free, multifunctional AERASGARD® RFTM - PS - CO2 - W room air quality measuring transducer with active/switching output, automatic calibration, in an elegant plastic housing with snap-on cover, base with 4-hole attachment, optionally with/without display, for detecting air humidity (0...100% r.H.), temperature (0...+50°C), particulate matter (PM)
