The Quantum® Oxidation Tester is the only field proven non-liquid RPVOT (formerly known as RBOT) instrument in the industry used for evaluating oxidation resistance over a broad range of oils and lubricants.

Widely used for base oil comparisons and as a condition monitoring tool for turbine oils.



Features & Benefits

  • Non-liquid ‘Dry-Cylinder’ sample heating — eliminates hot, hazardous, liquid bath mess and odor.
  • Software package monitors and records up to four (4) Quantum® instruments at the same time or separately.
  • Rapid turn-around in test capabilities due to independent sample testing — estimated to double productivity with multi-unit setup.
  • Front-loading, easily accessible pressure chamber.
  • Small, bench-top footprint.
  • Simple venting of odors through tubing to scrubber or vent — does not require placement in hood.
  • Advanced research capabilities for other applications with the Sample Temperature Probe and Sample Extraction Device.
