Seta Auto-Oxidation Stability Bath – 15400-5

This unit measures the induction period for oxygen in gasoline, and allows the weight of gum and residue in aviation fuel to be determined by direct weighing.

Comprising a heated water bath with reflux condenser, a cold water plunge tank for cooling test vessels after each test, and an integral system for charging oxidation vessels prior to test. The Seta Auto-Oxi Control System (15452-2) provides automatic monitoring of up to four pressure test vessels. High-quality pressure transducers and system components ensure reliable operation and fully traceable results.

Methods: ASTM D525, ASTM D873, ASTM D5304, IP 40, BS 2000-138 & IP 138, BS EN ISO 7536 & BS 2000-40 & ISO 7536


  • Operating temperature of 100°C
  • Water Bath with integral condenser
  • 4 x test stations
  • Cold plunge bath
  • Seta Auto-Oxi Automatic Pressure Monitoring
  • Integral vessel charge system
  • Constant level device

The Seta Auto-Oxi Control System (15452-2) is programmed with pressure/time test profiles for ASTM D525, D873, IP 40 and ISO 7536 allowing rapid test selection and start. Alternatively, custom test profiles are easily programmed by the user via the ‘Settings’ tab on the display screen.
Sample/operator details can also be input.

The recorded pressure status of each test vessel being monitored is displayed and the software automatically follows the pressure check and test sequence laid down in the test method, the displaying shows the ongoing test status of each vessel as well as the duration of the test remaining. Once a test starts, the system is designed for unattended operation and automatically reports the induction period (pressure drop) of each sample under test.

Results can be printed or downloaded via a USB interface.
