Measuring carbonation

[HairyDogBrewing]

Is there a way to objectively determine the actual carbonation level of a finished beer?
I force carb in corny kegs, using the carbonation chart.
But how could I measure the carbonation in a commercial beer?

Yes. Check Zahm and Nagel's website. They sell devices for testing beer drawn from a bulk tank and for beer in bottles and cans. The concept is the same in both cases. You pierce the bottle/can with a needle, shake it up and measure the pressure on a gauge connected to the piercing needle then check the temperature or fill a stainless steel "bottle" with beer from the bright tank (or whatever) shake it up and then measure its temperature and pressure. You then enter the same temperature/pressure/volumes chart you use to select the pressure for your keg beers and take out the volumes.
