Spesifikasi Koehler K12330 Oxidation Stability Apparatus 30-Place and 60-Place


Conforms to the specifications of: ASTM D943, D2274, D2893*, D4310, D6158; ISO 4263, 12205 AOCS CD12-57*; DIN 51586, DIN 51587; NF M 07-047; NF T 60-150

Temperature Control Stability: ±0.1°C (±0.2°F)

Oxygen Flow Rate: 3L/h to each test cell, individually controlled

Bath Capacity:

30-place model: 60 gal (227L)

60-place model: 114 gal (432L)


  • Thirty and sixty-place liquid baths for high volume testing requirements

  • Conforming to ASTM and related test method specifications

  • Special baths for ASTM D2893 and AOCS CD12-57 tests

Test Method

Evaluates oxidation stability by subjecting the sample to a temperature of 95°C in the presence of oxygen or dry air. For inhibited mineral oils, the sample is reacted with oxygen in the presence of water and an iron-copper catalyst.


Constant temperature water baths for high volume oxidation stability applications. Provides temperature control, metered air flow and condenser water supply controls for as many as thirty or sixty cells in a single system, eliminating the need for multiple water and electrical feeds and oxygen supply tanks. Microprocessor PID control provides quick temperature stabilization without overshoot, and the bath is protected by a redundant overtemperature control circuit that interrupts power should bath temperature exceed a programmed cut-off point.

Electrical Requirements

30-place model: 220-240V 50/60Hz, Single Phase, 28A

60-place model: 220-240V 50/60Hz, Single Phase, 54A
