Solvent-Resistant Oxygen Probe


  • Works in many polar and nonpolar solvents
  • Protected sensor tip by needle
  • Needle diameter/ length: 1.5mm / 40mm
  • No oxygen consumption

The solvent-resistant oxygen sensor measures oxygen partial pressure in most polar and nonpolar solvents (except fluorinated and some chlorinated hydrocarbons). Short-term applications up to 60 min in pure organic solvents and their mixtures are possible. A list of tested and compatible solvents is included in the data sheet, which is available in the Downloads tab. For repeated short-term measurements the sensor needs to be recalibrated. For a fixed tip solvent sensor, refer to the OXSOLV.

Standard range. This sensor is specified for a measuring range of 0 to 200 hPa oxygen. For detailed specifications, see the respective data sheet in the Downloads tab.

Protected tip. The very sensor tip is positioned exactly within the bevel of a beveled needle tip giving mechanical protection. This type is especially designed for performing oxygen measurements in gas samples after sensor insertion through rubber septa or packaging material (paper, plastics, aluminum packages). The needle is filled with glue ensuring no air leakage through the needle when puncturing packaging material. Application in liquids is possible, but requires special precautions in order to remove "trapped" gas bubbles at the sensor tip.

Solvent-resistant. For short-term application up to 60 min in specific (non-) polar solvents and solvent mixtures.

ST-connector. This connector is our standard sensor connector for sensor compatible PC-operated and handheld FireSting devices.

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.

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.
