food, pharmaceutical and medical device companies will now be able to improve the accuracy of their package headspace oxygen readings.optech®o2 model p test system uses a patentpending pressure needle&trade and a sensor to automatically measure internal package pressure and calculate the correct oxygen reading. internal package pressure directly impacts the accuracy of the oxygen reading.optecho2 technology relies on an optical sensor that &ldquofluoresces&rdquo or gives off light directly related to the amount of oxygen present in the package headspace.optecho2 model p is a useful tool for measuring oxygen permeation rates down to 1ccm2day.
