Fixed Fiber Oxygen Minisensor

OXF1100

  • Fixed sensor tip surrounded by needle
  • Sensor tip protrudes ca. 2mm
  • Works in gas (%O2) 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:

  • Measurement of respiration rates, best suited for salt water applications
  • Gas-tight sensor for measurements in incubations of enclosed samples like sediment, insertion through port

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% O2. For detailed specifications, see the respective pdf file in the Downloads tab.

Fixed fiber. The fragile sensor tip protrudes ca. 2mm from a straight-cut needle. They can be applied in liquids and in gases. The complete inner space of the syringe needle is carefully filled with glue, minimizing any gas reservoir which might slow down the response time of the sensor.

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.

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.
