You can use a lamda sensor in the exhaust which you can either hook up to an air / fuel ratio meter (about £30) or just measure the voltage across the signal wire to earth. Correct mixture should be about 0.5v.

The machine will give live reading at test but it'll depend how well you know the tester as to wether he'll let you fiddle while he's testing.
