D02 Sensor

D02 Sensor, a Dissolved Oxygen Sensor (DO2). The next generation in trouble-free oxygen sensing design from the Seametrics stable of smart sensors. It utilises fluorescence of a stable, immobilised ruthenium-based film matrix. So this DO2 sensor provides precision optical transmission and detection to measure oxygen concentration in a fluid.
