Air-Fuel Ratio Modules (AFR, FAR, %O2 & Lambda)

For applications where a display is not required, Labcell offers the ECM AFR modules.


Modules AFM1500 and F/A1500 output AFR (or FAR) via a 0 to 5V linearised analogue signal plus AFR, FAR, Lambda and %O2 via a SMB (Serial Measurement Bus) interface.

Modules AFM1000 and F/A1000 output AFR (or FAR) via a 0 to 5V linearised analogue signal.

The AFM1540 is the latest development of module designed specifically to operate with the Bosch LSU4.9 Sensor.


The OXY6200 module is suitable for %O2 measurements in the exhaust and intake of engines and outputs %O2 via a 1.1 to 5.5V linearised analogue signal.


The SMB interface allows serial communication with as many as sixteen modules using a single RS-232 serial port from a computer.


All modules use UEGO (Universal Exhaust Gas Oxygen) sensor and can perform field calibration of the system using ambient air.
