Abstract
An apparatus and method for extracting and measuring a gas sample from a package. The apparatus includes a hollow needle for puncturing the package, a suction pump for withdrawing a gas sample, and an intermediate sensor and valve to receive and direct gas flow through the system. The method includes puncturing the package, activating the suction pump for a predetermined time, equalizing the pressure drop across the sensor, and measuring the gas oxygen content.
