PreSens - Oxygen Microsensors

Needle-type oxygen microsensors are miniaturized chemical optical oxygen sensors designed for all research and packaging applications where a small tip size (< 50 µm) and fast response time (t90 < 1s) are necessary. The optical oxygen microsensors are based on a 140 µm silica fiber  and are available with two different sensor tip diameters, a < 50 µm tapered tip and a 140 µm flat-broken tip. The oxygen microsensors are mounted in different housings (needle-type housing, implantable) and offer a unique research tool for investigating systems where micro-invasive, small and robust sensors are needed.
