HK-2004 Air release value apparatus conforms to the ASTM D3427 standard Test Method for Air Release Properties of Petroleum Oils. It is used to test the ability of turbine, hydraulic, and gear oils to separate entrained air. This apparatus measures the time for the entrained air content to fall to the relatively low value of 0.2 % volume under a standardized set of test conditions and hence permits the comparison of the ability of oils to separate entrained air under conditions where a separation time is available. The significance of this test method has not been fully established. However, entrained air cancause sponginess and lack of sensitivity of the control of turbine and hydraulic systems. This test may not be suitable for ranking oils in applications where residence times are short and gas contents are high -
This apparatus conforms to the ASTM D482 Standard Test Method for Ash from Petroleum Products,it is used for determination of ash in the range 0.001–0.180 mass %, from distillate and residual fuels, gas turbine fuels, crude oils, lubricating oils, waxes, and other petroleum products, in which any ash-forming materials present are normally considered to be undesirable impurities or contaminants . The apparatus is limited to petroleum products which are free from added ash-forming additives, including certain phosphorus compounds. -
HK-1040A Automatic Total acid value titration for jet fuel conforms to the ASTM D3242 Standard Test Method for Acidity in Aviation Turbine Fuel.

HK-1033 Colorimeter for petroleum products conforms to the ASTM D1500 Standard Test Method for ASTM Color of Petroleum Products (ASTM Color Scale). The apparatus covers the visual determination of the color of a wide variety of petroleum products, such as lubricating oils, heating oils, diesel fuel oils, and petroleum waxes. experimenter pours different kinds of lubricating oil, kerosene, diesel and other petroleum product samples into colorimetric cylinder, then compare with normal glass color piece, determining the colourity by the corresponding colour number. -
HK-1024 Dean- Stark distillation tester conforms to the ASTM D 95 Standard Test Method for Water in Petroleum Products and Bituminous Materials by Distillation.The apparatus is used for testing water in the range from 0 to 25 % volume in petroleum products, tars, and other bituminous materials by the distillation method. -
HK-1022 Reid Vapour Pressure Bath conforms to ASTM D323 Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method). It used for testing the vapor pressure (Because the external atmospheric pressure is counteracted by the atmospheric pressure initially present in the vapor chamber, the Reid vapor pressure is an absolute pressure at 37.8°C (100°F) in kilopascals (pounds-force per square inch). The Reid vapor pressure differs from the true vapor pressure of the sample due to some small sample vaporization and the presence of water vapor and air in the confined space) of gasoline, volatile crude oil, and other volatile petroleum products -
HK-1020 Copper Strip Tarnish Test Apparatus conforms to the ASTM D130 standard . the apparatus can determinate of the corrosiveness to copper of aviation gasoline, aviation turbine fuel, automotive gasoline, cleaners (Stoddard) solvent, kerosine, diesel fuel, distillate fuel oil, lubricating oil,and natural gasoline or other hydrocarbons having a vapor pressure no greater than 124 kPa (18 psi) at 37.8°C (930mmHg). It is a good laboratory special-purpose instrument in petroleum chemical industry, transportation, scientific research colleges and universities. -
