Used to determine oxidation stability of mineral insulating oils by measuring the amount of sludge and acid formed under prescribed accelerated aging conditions

Device has a capacity of six samples, oxygenated by six independent flowmeters mounted on a common manifold. Insulated double-wall stainless steel bath features microprocessor temperature control with °C/°F switchable digital set point and display. Built-in control circuit interrupts power to the unit if bath temperature exceeds a programmed cut-off point.
