Ocean Optics sensor systems are ushering in a new generation of low-cost, portable chemical-sensing devices. Thanks to innovation in the development of chemical-sensing complexes -- particularly those with fluorescing properties -- products such as our Oxygen Sensor systems will continue to provide viable alternatives to traditional chemical-sensing devices such as electrodes. The use of optical-sensing methods lessens the reliance on the electrochemical technologies that have dominated the field of oxygen sensing.

Honeywell's high accuracy oxygen sensor range employs two ZrO2 discs with a small, hermetically sealed chamber between the discs. The first disc functions as a reversible oxygen pump, which successively fills and empties the chamber. The second disc measures the ratio of the partial pressure difference and generates a corresponding voltage. A heat element produces the 700 °C required for the ZrO2 to operate as an O2 pump. The time needed for the pump to achieve specific minimum and maximum pressures within this chamber provides a measure of the partial oxygen pressure of the environment.
Best Used For:
Industrial process and aircraft on-board oxygen generation system control, automotive exhaust gas diagnostics, service instruments, environmental oxygen monitoring, agriculture, combustion systems and environmental control.

Alphasense Oxygen Sensors operate using well-known fuel cell technology. The O2-A3 (3-year warranty), O2-A2 (2-year warranty), O2-A1 (1-year warranty), O2-G2 (2-year warranty)and O2-G1 (1-year warranty),sensors are designed for the latest generation of portable gas detectors where high detection performance, total reliability, small size and long lifetime are the key criteria.
All Alphasense sensors pass through our unique ATAV system (Automatic Test and Validation), which provides 100% traceability for you and your customers. Our sensors can also be supplied with a customised test report to individual requirements. A record of each sensor's performance is stored in the Alphasense database, accessible via the sensor barcode. This can be made available as hard copy evidence and also provides a powerful diagnostic tool.

The remarkable features of this oxygen sensor are its extremely long service life and the low maintenance costs due to its long-term adjustment and cleaning intervals.
The adjustment can be done in air or in saturated water without any calibration tables. The replacement of the galvanic cell is simplified by the design of the sensor. The membrane is very durable and is almost unbreak-able (100 µm membrane thickness).
Newly developed sensor electronics enable the oxygen sensor to work without an additional storage battery. The sensor can be modified to customer's needs regarding measuring range and accuracy.
The response time is less than 2 minutes.
The sensor can be immersed directly in water courses or tanks and does not need regular maintenance. The sensor is also available in combination with a temperature sensor.

Japan Storage Battery has developed the galvanic cell type oxygen sensor based on its technologies in fuel cells and lead-acid batteries. While the conventional galvanic cell type oxygen sensor was affected by CO2 and its life was short, because an aqueous solution of KOH was used as the electrolyte, our oxygen sensor using a weak acid electrolyte is not affected by any acidic gas and its life is 10 to 20 times as that of the conventional sensor.
Therefore, our oxygen sensor will find new and wide range of applications.
