Specification
Conforms to the specifications of:
ASTM D2440
Capacity: Six samples
Temperature Range: ambient to 260°F (127°C)
Circulator: 1⁄20hp impeller
Bath Capacity/Medium: 2.5 gal (9.5L) white technical oil
Description
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 flowmeters 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 overtemperature control circuit which automatically interrupts power to the unit when bath temperature exceeds a programmed cut-off point.
Test Method
Determines oxidation stability of mineral transformer oils by measuring the amount of sludge and acid formed under prescribed accelerated aging conditions.
