Robust Oxygen Probe

OXROB10-CL4-SUB

  • Stainless steel 10cm long, 3mm in diameter
  • 4m cable length (CL4)
  • With underwater SUB-connector (SUB)
  • Optically isolated (OI)
  • 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 robust oxygen probe is based on optical detection principles (proven REDFLASH technology) and can be used for precise bulk measurements in gas samples (O2 gas), stirred liquids (dissolved oxygen, DO) and in respirometry of e.g. fish.

Typical application:

 

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.

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 avoid interferences with the measurements.

SUB-connector (-SUB). Underwater sensor connector (instead of standard ST-connector) needed for applications with underwater devices.

4m cable length (-CL4). Cable length of ca. 4m, instead of standard 2m cable length.

longer cable length. Longer cable length is available on request.

 

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.
