  • auto-ranges switch between %vol and %LEL measurement, so always operating to correct parameter  

Gas-Pro TK keeps you up-to-the moment with on oxygen concentrations in the tank; telling you when the oxygen level is are

  • low enough to load and store fuel safely
  • high enough for safe tank entry
