Application
Carbon monoxide is a deleterious gas with colorless and odorless character , which could be absorbed by lung quickly, the speed rate of combination of CO and hemoglobin more 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 around the world.
G02-CO is used to monitor room carbon monoxide level as well as temperature and optional humidity. With one dry-contact of relay output, it cancontrol a ventilatoraccording the setpoint of carbon monoxide.
With the Modbus RS-485 communication interface, it can be connected with a DDC/PLC or a PC.
u Indoor air quality detection
u Industrial environment
u Underground parking lot, maintenance garage
u Freezing machine room and other places
