The fiber-optic oxygen sensors from PyroScience feature no oxygen consumption, no stirring sensitivity, an extremely long shelf time, resistance to corrosive environments (e.g. seawater) and are suitable for multiple applications in gas, water and aqueous samples.

This fiber-optic minisensor consist of an optical fiber with a sensor tip diameter of 430 µm. Compared to a microsensor, this sensor is suited for slightly larger samples, long-term measurements and profiling applications with less spatial resolution requirements.

Trace range. Trace range versions are available for high precision measurements close to 0% oxygen. They offer about 5x higher resolution compared to standard range oxygen sensors. The specified measuring range is 0-10% oxygen, with calibration at 0% oxygen and ambient air (21% oxygen), ensuring a straightforward calibration without the need of special calibration standards.

Retractable fiber. The actual sensor tip is surrounded by a 40 mm long syringe needle and can be moved out with a unique 4-step sliding mechanism. When retracted into the needle, the sensor tip is protected giving maximum protection while handling the sensor or while penetrating packages or a septa. The complete sensor is resistant to corrosive environments (e.g. seawater), as all metallic parts are made of stainless steel.

ST-connector. This connector is our standard sensor connector for sensor compatible PC-operated and handheld FireSting devices.

Easy calibration. A simple ambient air calibration can be performed with a few clicks (<1 minute for equilibrated setup). For precise oxygen measurements close to 0% we also offer easy-to-use calibration capsules (OXCAL). Simply dissolve the content of one calibration capsule in 50 ml distilled water, wait 10-15 minutes, perform the 0% calibration and start measurements with a calibrated sensor. For detailed calibration recommendations refer to the manual in the downloads tab.

Standard stock item. This item is typically in stock and small numbers can be shipped quickly. This does not apply for larger amounts, which ship with standard delivery time.
