The OpTech®-O2 Model P replaces the OpTech®-O2 Platinum. It measures oxygen permeation, headspace, dissolved oxygen and package leak. It is the ideal multi-application oxygen analyzer for food, beverage, pharmaceutical and medical applications where measuring oxygen and understanding its effect on product shelf life is critical. In addition, the Model P offers the new Pressure Needle which enables the the instrument to automatically compensate for internal package pressure.

Internal package pressure directly impacts the accuracy of the oxygen reading with optical fluorescence instruments. For example, if the internal package pressure is half the ambient pressure and is not compensated for by the instrument, the oxygen percentage will falsely read half the actual percentage in the package. Conversely, if the internal package pressure is twice the ambient pressure, the oxygen percentage will falsely read two times higher than the actual percentage. Incorrect oxygen readings directly impact the projected shelf life requirements. 

In all other aspects the Model P is identical with the Platinum version. Internal package pressure has always been able to be entered manually and is available on the Model P.
