Robust Oxygen Probe

OPROB3

  • Stainless steel 3cm long, 3mm in diameter
  • 1m fiber length, PICO-connector
  • Works in gas (%oxygen) and liquids (DO)
  • No oxygen consumption
  • Optically isolated (OI)
    ******will be discontinued on 1st April 2024*********

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 robust oxygen probe is based on optical detection principles (proven REDFLASH technology) and can be used for precise bulk measurements in gas samples (oxygen gas), stirred liquids (dissolved oxygen, DO) and in respirometry of e.g. fish.

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.

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

PICO-connector. This sensor connector is specially designed for the OEM oxygen meter PICO-O2.

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.
