PRECISION PETROLEUM TESTING INSTRUMENTS

Indiana Stirring Oxidation Test (ISOT) – JIS K 2514

 

The Lawler model ISOT is semi-automated and specially designed to perform the Indianna Stirring Oxidation Test.  ISOT is used for the evaluation of the oxidation stability of conventional oils.

This instrument has two test positions with individually heated tubes. The great advantage of the heated tube technology is it eliminates the need for using expensive and hazardous bath medium making it completely liquid free. Also, each position has individual precision stirrer motors with near perfect rpm accuracy and temperature probes.  This allows both test positions to be run independently.  Meaning the operator can start and stop either position without affecting the other. Finally, each position’s temperature and stirrer speed is controlled by a microprocessor based control system.  This system has a touch screen interface specifically designed to be user friendly.

For increased safety, inside the instrument are two high limit temperature controllers to prevent over heating.
