• Oxidation Stability Bath for Mineral Insulating Oils

Oxidation Stability Bath for Mineral Insulating Oils

Determines oxidation stability of mineral transformer oils by measuring the amount of sludge and acid formed under prescribed accelerated aging conditions.

  • 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 flowmeters mounted on a common manifold. Insulated double-wall stainless steel bath has microprocessor temperature control with °C/°F switchable digital setpoint and display. The operator and equipment are protected by an over-temperature control circuit which automatically interrupts power to the unit when the bath temperature exceeds a programmed cut-off point.
