HK-3536C Automatic Cleveland Open Cup Flash Point Tester conforms to ASTM D92, ISO2592. It is suitable for petroleum products with open cup flash point higher than 79℃ except fuel oil (fuel oil is usually measured according to ASTM D92).

HK-261B Automatic Pensky-Martens Closed Cup Flash Point Tester conforms to ASTM D93 Standard Test Methods for Flash Point by Pensky-Martens Closed Cup Tester. It is used to test for those liquids which have a kinematic viscosity of 5.8mm 2/s (cSt) or more at 37.8℃ or 9.5mm 2/s (cSt) or more at 25℃ (77℉), or that contain suspended solids, or have a tendency to form a surface film while under test. Other classification flash points have been estabilished by these departments for liquids using these test methods.

HK-8018A Automatic Gasoline Oxidation Stability Tester (Induction Period Method) conforms to ASTM D525 Standard Test Method for Oxidation Stability of Gasoline (Induction Period Method).It is used to test the stability of gasoline in finished form only,under accelerated oxidation conditions.(Warning This test method is not intended for determining the stability of gasoline components,particularly those with a high percentage of low boiling unsaturated compounds,as these may cause explosive conditions within the apparatus.)

HK-3535A Solidifying, Pour, Cloud & Cold Filter Plugging Point Tester is suitable to the standards of ASTM D 3944, ASTM D97, ASTM D2500 & ASTM D6371. It is used to test the solidifying, pour, cloud and cold filter plugging point of petroleum products.

HK-5096D Copper Strip Corrosion Tester for Petroleum Products conforms to ASTM D130 Standard Test Method for Corrosiveness to Copper from Petroleum Products by Copper Strip Test and ASTM D4048 Standard Test Method for Detection of Copper Corrosion from Lubricating Grease.It can test the resistance to the copper corrosion of aviation gasoline,jet fuel,motor gasoline,natural gas and other HC of which RVP is not higher than 124KPA,megilp,diesel,kerosene,distillate fuel oil,lubricating oil and lubricating grease.It can replace the water tank in plateau areas where the atmospheric pressure is low.It was awarded the "Utility Model Patent Certificate" on November 10, 2017.

HK-0689 Ultraviolet Fluorescence Sulphur Tester adopts advanced total sulfur analysis method--ultraviolet fluorescence method, determine the total sulphur content of various kinds of gas,liquid, solid oils and chemical product.It is a apparatus with high sensitivity, stable property, low detection lower limit, accurate test result, good repeatability.The apparatus conforms to the ASTM D5453.

The CCS apparent viscosity of automotive engine oils correlates with low temperature engine cranking. CCS apparent viscosity is not suitable for predicting low temperature flow to the engine oil pump and oil distribution system. Engine cranking data were measured by the Coordinating Research CouncilThe measurement of the cranking viscosity of base stocks is typically done to determine their suitability for use in engine oil formulations. A significant number of the calibration oils for this method are base stocks that could be used in engine oil formulations.

HK-0193 Automatic Lubricating Oil Oxidation Stability Tester (Rotating Oxygen Bomb Method)）conforms to ASTM D2112 and ASTM D2272

HK-3498A Automatic High Temperature Dropping Point Apparatus conforms to the ASTM D2265 Standard Test Method for Dropping Point of Lubricating Grease Over Wide Temperature Range.This apparatus covers the determination of the dropping point of lubricating grease and it tests dropping points of lubricating greases at temperatures of up to 400℃.It was awarded the "Utility Model Patent Certificate" on August 31, 2016.
