Jet Fuel Thermal Oxidation Tester

Model : JFTOT IV
Brand : Alcor

  • Sample and waste containers with quich coupling cover to minimize jet fuel vapor exposure to operators and to the environment
  • Sliding test door prevents exposure to the hot heater tube test section
  • Priming the pump, monitoring sample flow, and aerating the sample, are now automated
  • Operator now only needs 10 minutes per test compared to the ~50 minutes required by previous instruments.
