Product Description
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.
~ Conforms to ASTM D943, D2274, D4310, and related specifications
~ 8 and 12 position benchtop liquid baths available
~ 30 and 60 position floor model liquid baths available
~ Custom configurations for D2983 and AOCS CD12-57 tests available
Constant temperature bath with solid state temperature control, calibrated flowmeters and condenser water manifold for oxidation stability tests on fuels and lubricants. Individual flowmeters and control valves for each oxidation cell deliver air flow at the rate of 3L/h. Condenser water manifold has individual control valves for each cell. Temperature controller provides quick temperature stabilization without overshoot, and the bath is 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. Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options. Double-wall insulated baths are equipped with copper immersion heaters and a 1/20 hp circulation stirrer. Stainless steel bath interior has a builtin support rack and overflow/drain to immerse the test cells at the required depth. Order oxidation cell glassware and accessories separately.
