NDIR CO2 sensors drift over time and require span verification on the schedule defined by the host facility, the AHJ, or ASHRAE 62.1 demand-controlled ventilation commissioning procedures. The 5 percent concentration is above the alarm thresholds typical for parking garage and brewery applications, making it suitable for both span verification and full-scale check. Confirm regulator compatibility and cylinder connection thread before ordering, since Macurco kits use a non-DOT calibration regulator.\u003c\/p\u003e\n\u003cp\u003eVerify panel\/device family compatibility before ordering.\u003c\/p\u003e","brand":"Macurco","offers":[{"title":"Default Title","offer_id":52004379492645,"sku":"CO2 5% VOL","price":110.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0785\/7648\/4645\/files\/2969052_798x798_63121087-1e08-4460-8f76-a630c6a7fab3.webp?v=1771347505","url":"https:\/\/fastalarmdistribution.com\/products\/macurco-co2-5-vol-carbon-dioxide-co2-cal-gas-cylinde","provider":"Fast Alarm Distribution","version":"1.0","type":"link"}
