AERASGARD® RLQ-CO2-W (LCD)Maintenance-free AERASGARD® RLQ - CO2 - W room air quality measuring transducer with active/switching output, automatic calibration (can be deactivated), in an elegant plastic housing with snap-on cover, optionally with/without display, for determining the CO2 content of the air (0...2000 ppm/0...5000 ppm), the quality in three VOC sensitivity levels (low/medium/high), the temperature (0...+50°C) as well as the relative air humidity (0…100% r.H.). The transmitter converts the measured values into a standard signal of 0-10 V or 4...20 mA (switchable).
