Hand O₂ is used for determination of headspace and dissolved oxygen content in packages. Micro-invasive measurements are enabled by sensor tips smaller than 140 µm. Main application is packaging quality control in pharmaceutical food and beverage industry, i.e., measuring oxygen concentration in blister packs, vials, tubes, and other modified atmosphere packaging technology.

Chemical-optical oxygen sensor is designed for all research and packaging applications where a small tip size (<140µm) and fast response time (t90<1s) are necessary. The oxygen micro sensor is mounted in needle-type housing for easy application. The instrument is equipped with specially designed needle holder, which is also used for calibration processes.
