KN-2272 Oxidation Stability Bath, RPVOT / RBOT / TFOUT
The apparatus conforms to ASTM D2112, ASTM D2272, ASTM D4742. It determines oxidation stability of new and in-service turbine oils and other industrial oils; it utilizes an oxygen-pressured vessel to evaluate the oxidation stability of new and in-service turbine oils having the same composition (base stock and additives) in the presence of water and a copper catalyst coil at 150°C.Read

KN-OXIDATE Metal Bath Oxidation Stability Tester
The estimate of oxidation stability is useful in controlling the continuity of this property for batch acceptance of production lots having the same operation. It is not intended that this test method be a substitute for Test Method D943 or be used to compare the service lives of new oils of different compositions.Read

KN-2440 Oxidation Stability Tester for Mineral Insulating Oil
The oxidation stability test of mineral transformer oils is a method for assessing the amount of sludge and acid products formed in a transformer oil when the oil is tested under prescribed conditions. Good oxidation stability is necessary in order to maximize the service life of the oil by minimizing the formation of sludge and acid.Read

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

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

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
