Test Method
Determines oxidation stability of mineral transformer oils by measuring
the amount of sludge and acid formed under prescribed accelerated
aging conditions.
Oxidation Stability Bath
. Conforms to ASTM D2440 specifications
. Microprocessor temperature control with digital display and
over temperature cut-off
. Six-sample testing capacity
Constant temperature oil bath for testing oxidation stability of mineral
insulating oils. Immerses six oil receptacles at the required depth per
ASTM specifications at 110°C ± 0.5°C, and controls oxygen flow to each
sample at the rate of 1L/h ± 0.1L/h through six independent flow-meters
mounted on a common manifold. Insulated double-wall stainless steel
bath has microprocessor temperature control with °C/°F switchable
digital setpoint and display. Operator and equipment are protected by an
over temperature control circuit which automatically interrupts power to
the unit when bath temperature exceeds a programmed cut-off point.
Communications software (RS232, etc.), ramp-to-set and other enhanced
features are available as extra cost options. Contact your Koehler
representative for information. Order bath thermometer drying tower and
catalyst separately
