Petroleum Oxidation Stability Tester Bath

Provides an indication of the tendency of gasoline and aviation fuels to form gum in storage. The sample is oxidized inside a stainless steel pressure vessel initially charged with oxygen at 100psi (689kPa) and heated in a boiling water bath. The amount of time required for a specified drop in pressure (gasoline) or the amount of gum and precipitate formed after a specific aging period (aviation fuels) is determined.

There are two different models, both equipped with low liquid level controllers in accordance with the latest ASTM specifications:
~ The two-unit water bath can be flush mounted in a table top if desired, and is equipped with an overflow standpipe/drain to maintain the proper depth when the pressure vessels are inserted, and a plated brass reflux condenser to minimize evaporation loss.
~ The six unit model can be used with water or oil as a bath medium, and has a fully digital touch screen controller that provides quick temperature stabilization without overshoot. The bath is also protected by a redundant overtemperature control circuit that interrupts power should bath temperature exceed a programmed cut-off point. Display provides actual setpoint temperature values in °C/°F format. Both models feature double-wall insulated construction with stainless steel tanks, support racks and port covers. Order thermometer separately.
