Oxidation Stability of Mineral Insulating Oil – ASTM D2440 | IEC 61125


Apparatus for Oxidation Stability of Mineral Insulating Oil

Apparatus for Oxidation Stability of Mineral Insulating Oil

Model 505-8 is an oil bath with 6 test positions accepting ASTM D2440 or IEC61125 test tubes and with 8 float in tube flowmeters and precision control valve delivering oxygen at 1 ±0.1 L/hr. It operates at max temperature of 125°C with ±0.2°C stability. Specify which test method with order.

The heavily insulated stainless steel bath is agitated by an electrical motor for temperature uniformity. An over temperature cut off circuit is provided in the event of primary controller failure and a float for protection against low oil level.

Models 505-4 and 505-12 are similar to Model 505-8 but with 4 and 12 test positions, respectively

  • Conforms to ASTM D2440 or IEC 61125 (Specify which with order)
  • Temperature Stability of ±0.2°C
  • Temperature Range of 40° to 125°C
  • Flowmeters with Precision Control Valve
