Test Methods: D943, D2274, D2893, D4310, D7462, EN 12205
Oxidation Stability Of Distillate Oils
  • Meets the requirements of ASTM D943, D2274, D2893, D4310, D7462, EN 12205 test methods
  • Digital indicating temperature control maintains �0.1�C stability
  • Agitated liquid bath from 4 to 60 test positions
  • Temperature range of 40� to 120�C"
  • Supplied with flow meter for each test position
  • Low level safety cut off switch
  • Available for either 115V, 208V or 220V, 50 or 60 Hz power

The Series 501 Liquid Baths meet the requirements of ASTM D943, D2893*, D4310, D6158, AOCS12-57* , ISO 4263, ISO 12205, IP 388, DIN 51 587, NF M07-047, NF T60-150 test methods (* modified version for these methods is available).

Each test position has one float-in-tube flowmeter positioned in front. The oxygen flow rate is maintained at 3 ± 0.1 L/hr with a micro precision valve. An oxygen pressure regulator is optionally available.

Temperature control is provided by a digital display PID controller providing stability of ± 0.2º C or better. In the event of primary controller failure the bath is protected by a secondary high limit controller. Useful temperature range is from 40° to 120°C.

The 30 or 60 positions are arranged in two back to back rows (15 or 30 positions each) or in straight line.

Floor models come standard with a on/off water valve for the condensers. Upon request other arrangements can be made for water flow for both bench and floor models.
