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-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-5800Z Automatic Lubricating Oil Evaporation Loss Tester (NOACK Test)

The evaporation loss is of particular importance in engine lubrication. Where high temperatures occur, portions of an oil can evaporate. Evaporation may contribute to oil consumption in an engine and can lead to a change in the properties of an oil. Many engine manufacturers specify a maximum allowable evaporation loss. Some engine manufacturers, when specifying a maximum allowable evaporation loss, quote this test method along with the specifications.Read more >

KN-972 Evaporation Loss for Lubricating Grease

The loss of volatile materials from greases and oils can adversely effect the original performance characteristics of a lubricant and therefore could be a significant factor in evaluating a lubricant for a specific use. Such volatiles can also be considered contaminants in the environment in which the lubricant is to be used. Correlation between results from this test method and service performance has not been established.Read more >
