Key Features

Benefits at a Glance

  • Digital PA 5-OBA programmable manometers
  • Pressure-certified oxidation vessels
  • 4 test places for parallel testing
  • PC-software for data handling

Convenient Operation

  • The PA 5-OBA is a programmable manometer with a digital display and pressure connection. It determines automatically the induction period and checks the leakage stability of the oxidation vessel before starting the test automatically.
  • Data can be transferred from the manometer to your PC via an USB interface (cable included)
  • The included PC-software PetroNet Standard allows to monitor the numerical and graphical data on the screen.
  • Convenient temperature reading with Pt1000 temperature sensor (optional) and correction of the induction period according to the used method

Customized User Flexibility

  • Available with liquid bath or dry-heat bath
  • Dongle to unlock the PA 5 Professional module of the PetroNet Standard software to allow full access to the programmable parameters of the PA 5 manometers (optional)
  • PA 5 manometer pressure calibrator (optional)
  • Dry-heat bath calibration set (optional)
  • Certified manometers available with manufacturer's calibration certificate or official (DKD) calibration certificate (optional)
  • Tool set to ease the pressure vessel opening and closing procedure (optional)
  • Support shelf for test vessel (optional)
