CO2 is measured using an optical NDIR sensor (non-dispersive infrared technology). The detection range is calibrated for standard applications such as residential and conference room monitoring. Air quality is measured using a VOC sensor (mixed gas sensor for volatile organic compounds). This determines the pollution of the room air by contaminated gases such as cigarette smoke, body vapors, breathing air, solvent vapors, emissions from parts of the building, etc. A low, medium or high VOC sensitivity can be set for the expected air contamination.","brand":"S+S Regeltechnik","offers":[{"title":"Default Title","offer_id":51255398400331,"sku":"1501-61B1-7321-500","price":469.19,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0861\/8626\/2859\/files\/RFTM-LQ-CO2-Display-ppm__baldur2_maxi-mL_4c_d51f850a-e134-4458-95c8-c151f14c8045.png?v=1769689569"},{"product_id":"raum-luftguetefuehler-raum-co2-und-luftqualitaetsfuehler-aerasgard-rlq-co2-modbus-modbus-rtu-1501-61b1-6001-500","title":"AERASGARD® RLQ-CO2-Modbus","description":"Multifunctional room climate sensor AERASGARD® RFTM-LQ-PS-CO2-Modbus (maximum expansion stage) with Modbus connection, in an attractive plastic housing with snap-on cover, lower part with 4-hole mounting, optionally with\/without display, type variant RFTM-CO2-Modbus optionally with\/without setpoint potentiometer.
