HZ-662 petroleum product distillation tester is designed and manufactured according to GB / T6536-97 test method. Suitable for natural gasoline (stable light hydrocarbons), automotive gasoline, aviation gasoline, jet fuel, special boiling point solvents, naphtha, kerosene, diesel, gas oil, and similar petroleum products.

Density refers to the mass of the substance contained in the unit volume at the specified temperature. The density of the petroleum product increases with the increase of carbon, oxygen and sulfur in its composition, and thus contains more arene, colloid and asphaltene has large density, and thus contains more cyclane has medium density, and thus contains more alkane has small density. Therefore, according to the density (or specific gravity) of petroleum products, the type and composition of oil can be judged at some extent. SCMD2001 petroleum products density tester follows national standards GB / T1884-92 Density Measurement ff Petroleum and Liquid Petroleum Products (Density Meter Method), and is mainly used for the density determination of transparent, low viscosity liquid and viscous liquid, with the characteristics of high temperature control precision, reliable stability and easy operation.

The instrument applies to the determination of the color of every type of lubricating oil and other petroleum according to ASTM D1500. During the usage of the measuring instrument, the sample of petroleum is injected to the colorimetric tube. Then the chromaticity and the color number are determined after the sample is compared with the standard color sheet.

Flash Point is the lowest temperature at which a liquid can form an ignitable mixture in air near the surface of the liquid. The lower the flash point, the easier it is to ignite the material. Nowadays, Flash point is used to say non-volatile or flammable substances whether exit highly volatile or flammable substances, and has been one of the most important parameters for petroleum products transportation, storage, operations, safety management. 
HZKS-3 Automatic open flash point tester is designed and made as per the National Standard of People’s Republic of China GB/T267- 88; GB/T 3536-2008; European standard;ASTM-D92, it is an advanced analytical instrument, mainly used to determine the open flash point of petroleum products. 

The Transformer Oil Interfacial Tension Tester is an indispensable tool for professionals in the power industry, offering unparalleled accuracy and reliability. It operates on the principle of measuring the force required to detach a droplet of oil from a water surface, a key indicator of the oil’s purity and its ability to insulate and cool the transformer effectively. High interfacial tension values typically signify good oil quality, while lower values can indicate contamination or degradation, necessitating timely maintenance or replacement.

Freezing point refers to the maximum temperature in which all liquid fluid stops flowing under the specified cooling conditions.
HZNQ-1101 Oil pour point Tester, is used in the determination of transformer oil, lubricating oil and light oil and freezing point values of all kinds of chemical raw materials, the instrument adopts the imported refrigeration compressor, refrigeration rate faster, refrigeration function stronger .Imported high precision sensor, high test precision. It is widely used in electric power, chemical industry, railway, petroleum and other fields.

The Kinematic Viscosity Tester operates on the principle of measuring the time it takes for a specific volume of liquid to flow under gravity through a calibrated capillary tube. This time is then used to calculate the kinematic viscosity, which is expressed in centistokes (cSt). The tester is equipped with advanced temperature control systems to ensure that measurements are taken at consistent and precise temperatures, as viscosity is highly temperature-dependent.
