Brief introduction:
QB2000N is a device that detects the presence of hydrogen sulfide gas in an area, often as part of a safety system. It is used to detect a gas leak and interface with a control system so a process can be automatically shut down.
It can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. It is important because there are many gases that can be harmful to organic life, such as humans or animals.
