LA+ CO2
Air quality sensor for measuring CO2, temperature and humidity outdoors and in areas requiring a high IP class (e.g. subway stations, tunnels, exhibition halls, cold chains and greenhouses as well as in production halls and warehouses). Default values can be adjusted via Thermokon USEapp. Devices with a relay option can be used as 2-point controllers or 2-stage controllers.
