LA+
Air quality sensor for measuring CO2, mixed gas (VOC), optionally temperature and humidity outdoors and in areas requiring high IP protection class (e.g. underground stations, tunnels, exhibition halls, cold chains and greenhouses as well as in production halls and warehouses). For devices with CO2 and VOC, every output can be configured to be a mixed output (selectable ratio between CO2 and VOC). Devices with a relay option can be used as 2-point controllers or 2-stage controllers.
