KN-94 Saponification Number Of Petroleum Products

KN-94 Saponification Number of Petroleum Products conforms to ASTM D94 Standard Test Method for Saponification Number of Petroleum Products. Petroleum products can contain additives that react with alkali to form metal soaps. Fats are examples of such additives. Also, certain used engine oils, especially from turbine or internal combustion engines, can contain chemicals that will similarly react with alkali. The saponification number expresses the amount of base that will react with 1g of sampleRead more >

KN-46 Apparatus for Wax Content

KN-46 Apparatus for Wax Content conforms to UOP46 Paraffin Wax Content of Petroleum Oils and Asphalts. This method is for estimating the paraffin wax content of petroleum oils and asphalts. Wax content is an empirical value dependent upon the conditions under which the wax is separated from the original material. In this method paraffin wax content is defined as the mass-percent of material precipitated when a solution of asphalt-free sample in methylene chloride is cooled to -30 C. The lower liRead more >

KN-EP600 Infrared Spectroscopy Oil Detector

KN-EP600 Portable Infrared Spectroscopy Oil Detector will extract oil substances in water with tetrachloroethylene, determine the total extract, then adsorb the extract with magnesium silicate, and determine oil after removing polar substances such as animal and vegetable oils. The contents of total extracts and petroleum are calculated by absorbance a2930, a2960 and a3030 at bands with wave numbers of 2930cm-1 (stretching vibration of C-H bond in CH2 group), 2960cm-1 (stretching vibration of C-Read more >

KN-1094 Automatic Water Reaction Tester for Jet Fuel

A sample of the fuel is shaken, using a standardized technique, at room temperature with a phosphate buffer solution in scrupulously cleaned glassware. The cleanliness of the glass cylinder is tested. The change in volume of the aqueous layer and the appearance of the interface are taken as the water reaction of the fuel.Read more >

KN-4693 Low-Temperature Torque Tester

KN-4693 Low-Temperature Torque Tester conforms to ASTM D4693 Standard Test Method for Low-Temperature Torque of Grease-Lubricated Wheel Bearings. This test method covers the determination of the extent to which a test grease retards the rotation of a specially-manufactured, spring-loaded, automotive-type wheel bearing assembly when subjected to low temperatures. Torque values, calculated from restraining-force determinations, are a measure of the viscos resistance of the grease. This test methodRead more >

KN-Titrate Automated TAN & TBN Titrator

New and used petroleum products can contain basic constituents that are present as additives. The relative amounts of these materials can be determined by titration with acids. The base number is a measure of the amount of basic substance in the oil, always under the conditions of the test. It is sometimes used as a measure of lubricant degradation in service; however, any condemning limits must be empirically established.Read more >
