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

ISO 20336 Apparatus for Total Sulfur of Solid Mineral Fuels
KN-20336 Apparatus for Total Sulfur of Solid Mineral Fuels conforms to ISO 20336 Solid mineral fuels----Determination of total sulfur by Coulomb titration method. In the presence of the catalyst, a weighed sample is combusted at 1150℃ in a stream of purified air. The sulfur oxides are formed and dissolved in the electrolytic solution. The sulfur dioxides are titrated by the iodine and bromine liberated from the electrolysis of the potassium iodide and potassium bromide solution. The quantity of the electricity consumed by electrolysis is integrated and used to calculate the content of sulfur dioxides. The instrument is calibrated with certified reference materials. The percentage of total sulfur in the sample is calculated according to the sulfur dioxides content and the prior calibration.
