Model: KR-93C

The rotating pressure vessel oxidation tester (RPVOT) which also called the rotating bomb oxidation test (RBOT) is used to determine the oxidation stability of turbine oil, lubricating oil and other petroleum oils.

This automatic lubricating oil oxidation stability instrument is designed and manufactured according to ASTM D 2272 and petrochemical industry standard SH / t0193 “determination of lubricating oil oxidation stability by rotating oxygen bomb method”. This instrument is used to evaluate the oxidation stability of new and used turbine oils with the same composition (base oil and additives) at 150 ℃. The oxidation stability of new mineral insulating oil containing 2,6-di-tert-butyl-p-cresol and (or) 2,6-di-tert-butyl-phenol antioxidant can also be rapidly evaluated at 140 ℃.

 

Instrument features

 

1. Bath form: in accordance with the latest ASTM D 2272 standard metal bath structure design. The metal bath does not need expensive silicone oil medium, which can reduce the bad smell emitted by the medium oil during the test. There is no oil fume, no heavy bullet body, and no complicated cleaning after the test. The desktop design has small volume, light noise, no need of fume hood, energy saving and environmental protection.

2. Instrument display: 7 inch color touch screen, beautiful interface, easy to operate. Temperature and pressure calibration.

3. Operation design: double independent design, make the test process has the ability of rapid turnover, in the case of using double equipment, can greatly improve work efficiency.

4. High degree of automation: automatic constant temperature, automatic oxygen flushing, automatic judgment of leakage, automatic recording of test data and real-time display of curve, automatic judgment of test inflection point, automatic cut-off of heating after test.

6. Special configuration: equipped with small winding machine to facilitate test preparation.
