Automatic Oxidation Stability Bath, RPVOT / RBOT / TFOUT
KN-OXIDATE Metal Bath Oxidation Stability Tester conforms to ASTM D2112 Standard Test Method for Oxidation Stability of Inhibited Mineral Insulating Oil by Pressure Vessel, ASTM D2272 Standard Test Method for Oxidation Stability of Steam Turbine Oils by Rotating Pressure Vessel, ASTM D4742 Standard Test Method for Oxidation Stability of Gasoline Automotive Engine Oils by Thin-Film Oxygen Uptake (TFOUT) and ASTM D942 Standard Test Method for Oxidation Stability of Lubricating Greases by the Oxygen Pressure Vessel Method. It determines oxidation stability of new and in-service turbine oils and other industrial oils; it is 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.

Rapid Small Scale Oxidation Stability Tester RSSOT
A 5 mL sample is introduced into a pressure vessel which is then charged with oxygen to 500 kPa at a temperature of 15 to 25°C. The test is initiated by starting the heater and heating the pressure vessel to a temperature of 140°C. The pressure is recorded continuously until the breakpoint is reached. Alternatively, the test may be terminated when a predetermined minimum requirement is reached

ASTM D525 Automatic 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 gasolines

ASTM D943 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.”

ASTM D2440 Mineral Insulating Oil Oxidation Stability Test
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.

ASTM D7153 Automatic Rapid Freezing Point Tester
KN-7153 Automatic Rapid Freezing Point Tester conforms to ASTM D7153 Standard Test Method for Freezing Point of Aviation Fuels (Automatic Laser Method). The freezing point of an aviation fuel is the lowest temperature at which the fuel remains free of solid hydrocarbon crystal which, if present in the fuel system of the aircraft, can restrict the flow of fuel through filters. The temperature of the fuel in the aircraft tank normally decreases during flight depending on aircraft speed, altitude, and flight duration. The freezing point of the fuel shall always be lower than the minimum operational fuel temperature.

ASTM D4294 XRF Sulfur Content Tester
This tester provides rapid and precise measurement of total sulfur in petroleum and petroleum products with a minimum of sample preparation. A typical analysis time is 1 to 5 min per sample. The quality of many petroleum products is related to the amount of sulfur present. Knowledge of sulfur concentration is necessary for processing purposes. There are also regulations promulgated in federal, state, and local agencies that restrict the amount of sulfur present in some fuels. This tester provides a means of determining whether the sulfur content of petroleum or a petroleum product meets specification or regulatory limits
