KN-4052M Electronic Liquid Density Meter [U-tube Oscillation Method]

KN-4052M Electronic liquid density meter [U-tube oscillation method] conforms to ASTM D4052 Standard Test Method for Density, Relative Density, and API Gravity of Liquids by Digital Density Meter. Density is a fundamental physical property that can be used in conjunction with other properties to characterize both the light and heavy fractions of petroleum and petroleum products.Read more >

KN-4052P Portable Density Meter

KN-4052P is used to measure the temperature and density (concentration) of the liquid in the tank. After the measurement, the data is automatically displayed, portable design. It is made for density and concentration measurement in harsh environments, including outdoor operation, while providing the accuracy expected from a lab instrument.Read more >

KN-3289 Density Of Asphalt Materials

The sample is placed in a nickel crucible and weighed in air, and then in water at the test temperature. The density is calculated from the mass of the sample and its apparent mass when weighed in waterRead more >

KN-156 Saybolt Chromometer

The height of a column of sample is decreased by levels corresponding to color numbers until the color of the sample is unmistakably lighter than that of the standard. The color number above this level is reported, regardless of whether the sample was darker, questionable, or a match at the higher levelRead more >

KN-6045 Colorimeter for Petroleum Products

KN-6045 Colorimeter for Petroleum Products conforms to the ASTM D6045 Standard Test Method for Color of Petroleum Products by the Automatic Tristimulus Method. Determination of the color of petroleum products is used mainly for manufacturing control purposes and is an important quality characteristic because color is readily observed by the user of the product. In some cases, the color may serve as an indication of the degree of refinement of the material. When the color range of a particular prRead more >

KN-7843 Membrane Patch Colorimetry

KN-7843 Membrane Patch Colorimetry conforms to ASTM D7843 Standard Test Method for Measurement of Lubricant Generated Insoluble Color Bodies in In-Service Turbine Oils using Membrane Patch Colorimetry. Insoluble deposits are extracted from an in-service turbine oil sample using a 47mm, 0.45μm membrane nitrocellulose patch. The color of the patch is then analyzed using a spectrophotometer and the results are reported as a △E value in the CIELAB scale.Read more >

KN-4530 Micro Carbon Residue Apparatus

The carbon residue value of the various petroleum materials serves as an approximation of the tendency of the material to form carbonaceous type deposits under degradation conditions similar to those used in the test method, and can be useful as a guide in manufacture of certain stocks. However, care needs to be exercised in interpreting the resultsRead more >

KN-189 Conradson Carbon Residue Tester

KN-189 Conradson Carbon Residue Tester conforms to ASTM D189 Standard Test Method for Conradson Carbon Residue of Petroleum Products. This apparatus covers the determination of the amount of carbon residue left after evaporation and pyrolysis of an oil, and is intended to provide some indication of relative coke-forming propensities. This test method is generally applicable to relatively nonvolatile petroleum products which partially decompose on distillation at atmospheric pressure, our KN-189Read more >

KN-524 Ramsbottom Carbon Residue Apparatus(Electric furnace method)

The carbon residue value of burner fuel serves as a rough approximation of the tendency of the fuel to form deposits in vaporizing pot-type and sleeve-type burners. Similarly, provided alkyl nitrates are absent (or if present, provided the test is performed on the base fuel without additive) the carbon residue of diesel fuel correlates approximately with combustion chamber deposits. The carbon residue value of motor oil, while at one time regarded as indicative of the amount of carbonaceous depRead more >

KN-5800BZ Semi-Automatic Lubricating Oil Evaporation Loss Tester (NOACK Test)

KN-5800BZ uses the automated Woods metal Noack evaporative apparatus. The evaporation loss is of particular importance in engine lubrication. Where high temperatures occur, portions of an oil can evaporate. , which is suitable for the determination of lubricating oil (especially Evaporation loss of engine oil) and lubricating base oil at 250 ℃.Read more >
