Constant temperature baths with solid-state temperature control, calibrated flowmeters and condenser water manifold for oxidation stability tests on fuels and lubricants. Evaluates oxidation stability by subjecting the sample to a temperature of 95°C in the presence of oxygen or dry air. For inhibited mineral oils, the sample is reacted with oxygen in the presence of water and an iron-copper catalyst. Individual flowmeters and control valves for each oxidation cell deliver airflow at the rate of 3L/h. Condenser water manifold has individual control valves for each cell. Microprocessor PID control provides quick temperature stabilization without overshoot.
