Demand-based ventilation, increased well-being and customer benefit, increased comfort and a reduction in operating costs through energy savings are just some of the results of using the AERASGARD® CO2. \u003cbr\u003e\u003cbr\u003eThe above explanations show that there are applications for CO2 measurements, applications for VOC measurements but, in our view, primarily applications for the combination of both measured variables. It is important to note that these two measured variables cannot be converted into each other or derived from each other. A CO2 transmitter with an NDIR sensor measures selectively and cannot detect mixed gases (VOC); a VOC sensor cannot detect CO2 molecules.","brand":"AERASGARD","offers":[{"title":"Default Title","offer_id":51255364026699,"sku":"1501-8116-7371-200","price":451.1,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0861\/8626\/2859\/files\/KFTM-LQ-CO2-W-350ppm-OC__tyr2-PA6-K_maxi-mL_4c.png?v=1769683605"},{"product_id":"kanalfuehler-fuer-feuchte-temperatur-luftguete-und-co2-aerasgard-kftm-lq-co2-w-0-10v-4-20ma-1-wechsler-24-v-wechsler-1501-8118-7301-500","title":"AERASGARD® KFTM-LQ-CO2-W","description":"Patented quality product (patent no.
