K12200 Oxidation Stability Apparatus, 8- & 12-Unit


 

Test Method
Evaluates oxidation stability by subjecting the sample to a temperature of 95C 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.


Features and Benefits

• Conforming to ASTM and related test method specifications


 

K12200 Oxidation Stability Apparatus, 8- & 12-Unit
Constant temperature baths 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. Microprocessor PID control 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 electronic solid state temperature control, copper immersion heaters and a 1/20 hp circulation stirrer to maintain temperature uniformity of 0.2C. Stainless steel bath interior has a built-in support rack and overflow/drain to immerse the test cells at the required depth. Order oxidation cell glassware and accessories separately.
