Gas detector - Wikipedia

A gas detector is a device that detects the presence of gases in an area, often as part of a safety system.This type of equipment is used to detect a gas leak or other emissions and can interface with a control system so a process can be automatically shut down. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave.
