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 trace oxygen probe is based on optical detection principles (proven REDFLASH technology) and can be used for precise bulk measurements in stirred/agitated water (dissolved oxygen, DO) at low oxygen conditions (<20% air sat. / 2 mg/L DO).
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.
Optical isolation. For applications at high ambient light (e.g. direct sunlight, illuminated samples) and in fluorescing / light-sensitive samples, an additional optical isolation (-OI) protection layer is added to the sensor surface to reduce enhanced sensor aging and to avoid interference with the oxygen measurements
ST-connector. This connector is our standard sensor connector for 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 100 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.
