Gas Sensors

Gas Sensors are designed to detect and respond to the presence or a change in the concentration of a gas. They are characterized by the type of gas being detected. Examples include: acetylene, alcohol, benzine, butane, ammonia, carbon dioxide, carbon monoxide, hydrocarbons, hydrogen, hydrogen sulfide, methane, natural gas, nitrogen dioxide, oxygen, ozone, propane, and sulfur dioxide.
