Collection: Indoor Air Quality (IAQ) and Combo Sensors

Indoor Air Quality (IAQ) directly impacts occupant health and productivity in commercial buildings. Poor ventilation and pollutants such as mold, VOCs, CO₂, and particulate matter can cause headaches, fatigue, and reduced performance — while well-managed air quality improves comfort and well-being. IAQ and combo sensors monitor these conditions and signal HVAC systems to automatically adjust for cleaner air. Combo sensors measure multiple parameters in a single device, with many models combining temperature and relative humidity, and others adding CO₂, CO, NO₂, or particulate matter monitoring. We carry IAQ and combo sensors from Senva, Gentex, Siemens, Greystone, and other trusted manufacturers.
