Koehler Instruments® K12290 8-Unit Oxidation Bath, 220 - 240V

8-Unit Oxidation Stability Apparatus, 220 - 240V. 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, 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 set point 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 ±0.2°C. Temperature Range: ambient to 212°F (100°C). 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. Conforms to the specifications of: ASTM D943, D2274, D4310, D6158; DIN 51586, DIN 51587; ISO 4263, ISO 12205. Dimensions (L x W x H): 17.5 x 25 x 42". 220 - 240V. 50/60Hz. Single Phase, 6.8A. Shipping weight: 137lb (62.1kg). Koehler #: K12200.
