LA+

Air quality sensor for measuring CO2, mixed gas (VOC), temperature and humidity outdoors and in areas requiring high IP protection class (e.g. subway stations, tunnels, exhibition halls, cooling and greenhouses as well as in production halls and warehouses). If required, default values can be adjusted via Thermokon USEapp. For devices with CO2 and VOC, each output can be configured to be a mixed output (selectable signal ratio between CO2 and VOC). Devices with a relay option can be used as 2-point controllers or 2-step controllers.

Measuring values CO2, VOC, temperature + humidity (depending on the device), types CO2+VOC: each output can be set to get a variable mix of CO2 and VOC by configuration via Thermokon USEapp
Output voltage 1..3x 0..10 V or 0..5 V (adjustable via jumper; live-zero configuration via Thermokon USEapp), min. load 10 kΩ
