Gas Detector

A gas detector is a safety tool that detects the gases presence in any area to ensure complete security against any gas leakage and fire. This has become an essential device to detect the leakage of any combustible material, flammable gases, toxic gases, oxygen depletion or any other emissions that can connect with a control system to automatically shut down the process. This can sound an alarm to make the operators aware in the area about the gas leakage and allowing them to evacuate the place before any mishap take place. It is widely used in oil rigs and other places to observe the manufacturing processes as well as emerging technologies like photovoltaic. It can also be used in firefighting.
