KN-943 Apparatus for Oxidation Characteristics of Inhibited Mineral Oils

KN-943 Apparatus for Oxidation Characteristics of Inhibited Mineral Oils conforms to ASTM D943 Standard Test Method for Oxidation Characteristics of Inhibited Mineral Oils. The oil sample is contacted with oxygen in the presence of water and an iron-copper catalyst at 95°C. The test continues until the measured acid number of the oil is 2.0 mg KOH/g or above. The number of test hours required for the oil to reach 2.0 mg KOH/g is the “oxidation lifetime.”Read more >

​KN-525Z Gasoline Oxidation Stability Tester

The induction period may be used as an indication of the tendency of motor gasoline to form gum in storage. It should be recognized, however, that its correlation with the formation of gum in storage may vary markedly under different storage conditions and with different gasolinesRead more >

KN-942Z Greases Oxidation Stability apparatus

This apparatus measures the change in pressure resulting from consumption of oxygen by oxidation and gain in pressure due to formation of volatile oxidation by products. It predicts neither the stability of greases under dynamic service conditions, nor the stability of greases stored in containers for long periods, nor the stability of films of greases on bearings and motor parts. It should not be used to estimate the relative oxidation resistance of different grease types.Read more >
