There used to be a "pinch" test, where they pinched different areas of your body (stomach, back of arm, etc.) with a special instrument that measured physical resistance, and looked up your BMI on a chart.
Now a days, a device that sends a small electric current through your body is used, as one guy above has already said.

They can use a mild electric current. Since fat conducts electricity differently than muscle, they can determine the percentage of fat. There are bathroom scales that can measure this, but they're expensive.
