Analog gauges are exposed directly to the source of their measurements, which in this case is the voltage output of an oxygen sensor. Fluctuations affect the needle proportionately, and these variations translate into accurate readouts. As a result, this mechanical gauge will immediately demonstrate any changes in the air/fuel ratio with pinpoint precision. Given the smooth needle movement, any rate of change can be detected very easily.
