Carbonmonoxide is a deleterious gas with colorless and odorless character , whichcould be absorbed by lung quickly, the speed rate of combination of CO and hemoglobinmore than 250 times with oxygen, then stops oxygen circulation around the body;which have big character of heavy toxicity, so carbon monoxide poisoning have became a big problem aroundthe world.
G02-CO isused to monitor room CO level as well as temperature and humidity options. Withone dry-contact of relay output, it cancontrol aventilatoraccording the setpoint of carbon monoxide.
With theModbus RS-485 communication interface, it can be connected with a DDC/PLC or aPC.
