interference methanometer
A combustible-gas detector based on the velocity of light. A beam of light is split into two parts that pass respectively through chambers containing pure air and the test air at velocities characteristic of the gases. When methane is present, the light beams are out of step and this movement becomes a measure of the methane concentration.
