Solvent-Resistant Oxygen Probe

  • Optical oxygen sensor for polar and nonpolar solvents
  • Measures dissolved oxygen partial pressure in most pure or complex organic solvents
  • Sensor tip 1.5 mm in diameter
  • Proven REDFLASH technology
  • No oxygen consumption
  • >3 years shelf time

The solvent-resistant oxygen probe OXSOLV measures oxygen partial pressure in most polar and nonpolar solvents (except fluorinated and some chlorinated hydrocarbons). It is based on optical detection principles (REDFLASH technology) and can be used for short-term applications in pure and complex organic solvents. A list of tested solvents is available on request. The sensor tip consists of a stainless steel tube 1.5 mm in diameter and 150 mm in length.
