FlameIR-ME1 is a new methane sensor that uses a solid-state LED optical technology and operates with a low energy consumption. The sensor is compatible with battery-powered operation, allowing the sensor to be used in a wide variety of applications, including wirelessly connected equipment. The device includes altitude-pressure compensation, real-time temperature correction and the ability provide either analog or digital methane measurements. The FlameIR-ME1 also features a built-in zero-tracking function to maintain CH4 measurement accuracy over the lifetime of the product. The sensor can be zeroed at power-on, and also periodically for applications that are permanently powered. Limits can be set on the amount of zero movement allowed, with the status flag used to indicate large changes from the initial calibration setting. Typical measurement accuracy is 0.01%. — Gas Sensing Solutions, Cumbernauld, U.K.
