From the manufacturer's datasheet for LA+ RS485 BACnet.
Overview
The LA+ measures CO2 and mixed gas (VOC), and on some versions temperature and humidity. It is made for places that need a high IP rating, such as tunnels, underground stations, exhibition halls, cold stores and greenhouses. It connects on RS485 BACnet MS/TP and also has active 0 to 10 V or 0 to 5 V outputs. On CO2 plus VOC versions each output can be set to a chosen mix of the two. A sun and rain shield is supplied.
