FDO2

The FDO2 oxygen sensor is a factory calibrated, robust, accurate, fast response, long lasting and almost maintenance free oxygen sensor for demanding gas sensing applications, e.g. for oxygen gas monitoring in glove boxes, portable equipment, exhaust gases, Mars rovers and more. Although the form factor is similar to conventional electro-galvanic oxygen sensors (oxygen fuel cells), the sensor operates on a completely different, an optical principle. The optical measurement is based on a propriatary luminescent sensor dye from PyroScience, which is sensitive to oxygen partial pressure. This principle is very robust and shows virtually no interferences to other gases. It does not deplete over time, unlike electro-galvanic oxygen sensors with their very limited shelf and operation life. Optics and electronics are hermetically sealed from the measured gas and the sensing surface is highly hydrophobic, so water droplets do not disturb the measurement. For typical indoor environmental conditions a 10 year operating life is expected.

The flow-through cell FDO2-FTC enables simple integration in a variety of gas-streams. The USB interface cable FDO2-USB comes together with a versatile evaluation software (more details under Accessories).

Outstanding Features
