Wide Band Oxygen (O2) A/F Sensor Calibration Checker
you can check your wide band O2 sensors and see if they have gone bad or your
engine is really running that lean.
You screw in your sensor and supply the nitrogen (or argon) gas, and the propane or shop air at the specified rate to produce most any A/F mixture, from 11:1 to as lean as 17:1. (These fittings are on the back side of the device in picture. Gases not included with calibrator.)
only do you check your sensor, but your entire A/F recording system, including
the electronics, wiring, computer or data logger and software calibration.
you can have confidence you’re getting accurate A/F numbers.
