Retractable Fiber Oxygen Minisensor

OXR430-HS

  • Retractable fiber 430µm in diameter
  • High speed response time (t90 < 0.8s)
  • Works in gas (%oxygen) and liquids (DO)
  • No oxygen consumption
  • Negligible drift, >3 years shelf time

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.

Typical applications:

Standard range. This sensor is specified for an optimum measuring range of 0 to 500 hPa oxygen (0 -250% air saturation). However, without specifications, it is possible to measure in up to 1 bar pure oxygen/100% oxygen saturation/100% oxygen. For detailed specifications, see the respective pdf file in the Downloads tab.

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.

High speed (-HS). Typical response times for 90% signal change (T90) in water and gas: <0.8 s. Measured for the transition from air into a stirred solution of 1% Na2SO3.

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.

Star sensor. This sensor is one of the world's best or only solutions in a certain application area, featuring for example a very fast response time, solvent resistance or a unique sensor format.
