KN-5185 ICP for used Lube Oils

22 elements in used lubricating oils and in base oils, and it provides rapid screening of used oils for indications of wear. Test times approximate a few minutes per test specimen, and detectability for most elements is in the low mg/kg range. In addition, this test method covers a wide variety of metals in virgin and re-refined base oils. Twenty-two elements can be determined rapidly, with test times approximating several minutes per test specimen.Read more >

KN-4951 ICP for Unused Lube Oils

Additive packages are blends of individual additives, which can act as detergents, antioxidants, antiwear agents, and so forth. Many additives contain one or more elements covered by this test method. Additive package specifications are based, in part, on elemental composition. Lubricating oils are typically blends of additive packages, and their specifications are also determined, in part, by elemental composition. This test method can be used to determine if additive packages and unused lubricRead more >

KN-6595 (RDE-AES) Rotary Disc Electrode Atomic Emission Spectrometer

Wear metals and contaminants in a used oil test specimen are evaporated and excited by a controlled arc discharge using the rotating disk technique. The radiant energies of selected analytical lines and one or more references are collected and stored by way of photomultiplier tubes, charge coupled devices or other suitable detectors. A comparison is made of the emitted intensities of the elements in the used oil test specimen against those measured with calibration standards.Read more >

KN-6595P Portable Rotary Disc Electrode Atomic Emission Spectrometer (RDE-AES)

KN-6595P Portable Rotary Disc Electrode Atomic Emission Spectrometer (RDE -AES) which is capable of directly testing the contents of various metallic elements in liquid samples, such as lubricating oil, hydraulic oil, fuel oil, and etc., and finishing the analysis of various elements with a single injection with a single injection within 2 minutes. No sample pretreatments, auxiliary gas or cooling water is needed before and during the instrument is operating. Because of the strong adaptability tRead more >

KN-7684 Dual Analysis Ferrograph

KN-7684 Dual Analysis Ferrograph conforms to ASTM D7684 Standard Guide for Microscopic Characterization of Particles from In-Service Lubricants. Periodic in-service lubricant samples are collected from a machine as part of a routine condition monitoring program. The sample is prepared to separated particles from the sample fluid. The separated particles are subsequently examined using an optical microscope to identify the types of particles present to aid in identifying the wear mode occurring iRead more >

KN-AAS Flame Furance Atomic Absorption Spectrophotometer

When fuels are combusted, metals present in the fuels can form low melting compounds that are corrosive to metal parts. Metals present at trace levels in petroleum can deactivate catalysts during processing. These test methods provide a means of quantitatively determining the concentrations of vanadium, nickel, iron, and sodium. Thus, these test methods can be used to aid in determining the quality and value of the crude oil and residual oil.Read more >

KN-4291 GC for Trace Ethylene Glycol in Used Engine Oil

Leakage of aqueous engine coolant into the crank case weakens the ability of the oil to lubricate. If ethylene glycol is present, it promotes varnish and deposit formation. This test method is designed for early detection to prevent coolant from accumulating and seriously damaging the engineRead more >

KN-13357 Lubricating Oil Filterability Tester

This instrument is produced in accordance with the Petroleum products - Determination of the filterability of lubricating oils - Part 2: Procedure for dry oils, and is used to determine the filterability of lubricating oil based on mineral oil, especially the hydraulic oil in the hydraulic system. It is not suitable for liquids based on other materials (such as flame-retardant liquids, because they may be compatible with the filter membrane used in this method); it is also not suitable for someRead more >

KN-5133 Gel Index Tester (LTLS)

KN-5133 Gel Index Tester (LTLS) conforms to ASTM D5133 Standard Test Method for Low Temperature, Low Shear Rate, Viscosity/Temperature Dependence of Lubricating Oils Using a Temperature Scanning Technique. This test method covers the measurement of the apparent viscosity of engine oil at low temperatures and ASTM D7110 Standard Test Method for Determining the Viscosity-Temperature Relationship of Used and Soot-Containing Engine Oils at Low Temperature. This Test method covers how to measure theRead more >

KN-40A Channel Point Tester for Gear Oil

KN-40A Channel Point Tester for Gear Oil conforms to FTMS-791B-3465.1 and SH/T 0030. It is used for determination of channel point of gear oil at low temperature. The test consists of storing an Oil sample for 18 hours at a low temperature, cutting a channel in the lubricants with a metal strip and determining whether the lubricants flow together to covet the bottom of the container within 10 seconds.Read more >
