Lambda PRO is one of the simplest air-fuel ratio analyzers used in ECM in the United States. It has many features of the air-fuel ratio analyzer AFRecorder1200, such as linearized analog output and maximum or minimum AFR recording. Using NTK AFR sensor, the measurement response is fast, compatible with gasoline and methanol fuels, and other fuels are available. Standard portable case and 13 foot cable (optional 35 foot extension cable).
