This instrument is a special test instrument designed and manufactured according to the national standard gb265-88 petroleum product kinematic viscosity measurement method. It is suitable for measuring the kinematic viscosity of liquid petroleum products.

This instrument has the time of timing sample movement, and calculates the final result of motion viscosity automatically.

This method is applicable to the determination of the kinematic viscosity of liquid petroleum products (i.e., Newtonian liquids). The unit is m2/s, which is usually used as mm2/s in practice.

The kinetic viscosity can be obtained by the measured kinetic viscosity times the density of the liquid.

Under this method is in a constant temperature, the determination of a certain volume of liquid under gravity flow through a calibration good glass capillary viscometer, the product of the capillary viscometer constant with the flow of time, as the temperature determination of kinematic viscosity of liquid.

The kinetic viscosity at the temperature and the density of the liquid at the same temperature are the dynamic viscosity of the temperature.

The Automatic Tektronix Closed-Cup Flash Point Tester is an advanced laboratory instrument designed and manufactured according to ASTM D56 standards, specifically for determining the flash point of petroleum products and other liquids.

Flash point is one of the important indicators for assessing the flammability of a substance. In transportation and safety regulations, it is used to define flammable and combustible substances, and it can also reflect whether there are highly volatile or flammable impurities in the substance.

This instrument is suitable for determining the flash point of liquids with a viscosity of less than 5.5 mm²/s (cSt) at 40°C (104°C) or less than 9.5 mm²/s (cSt) at 25°C (77°C) using a Tiger closed-cup tester, and a flash point below 93°C (200°F).

The HZ1151 fully automatic apparent viscometer (CCS) complies with technical specifications such as GB/T6538-2010 and ASTM D5293; it is suitable for testing the low-temperature dynamic viscosity index of engine oil. The instrument can measure the apparent viscosity of oil at a temperature of -35°C to -5°C with an interval of 5°C. It has the advantages of accurate measurement, good repeatability, stable performance and simple operation.

It is suitable for measuring the apparent viscosity of engine oil at a shear stress of about 500 to 20000 mPa.s and a shear rate of 105 to 104 S-1 at -5°C to -30°C. The instrument uses fully automatic temperature control equipment, users only need to operate on the color touch screen to quickly and easily perform testing and analysis.

The device is controlled by the single-chip microcomputer , with a high degree of automation, automatic discharge functions. It is a test instrument of high precision, simple, direct way to achieve fast transformer measurement.

The transformer oil filter is a mechanical device specifically designed for filtering and purifying transformer oil. Its core function is to remove solid impurities, water, and gases from the oil, thereby improving the oil's quality and enhancing the insulation strength of the transformer oil.

The HZKC-50 series equipment is used to evacuate the gas from the transformer, so that the iron core, coil, and insulating materials inside the transformer are completely exposed to a high-vacuum environment. In this high-vacuum environment, the moisture absorbed by the iron core, coil, and insulating materials evaporates into the air and is then discharged by the vacuum pump. This process achieves the function of drying the transformer.

The flash point is the lowest temperature at which a liquid can form an ignitable mixture in air near its surface. The lower the flash point, the easier it is to ignite the material. Nowadays, the flash point is used to determine whether non-volatile or flammable substances contain highly volatile or flammable components. It has become one of the most important parameters for the transportation, storage, and safety management of petroleum products.

The Automatic Closed Cup Flash Point Tester is designed and manufactured in accordance with the National Standards of the People’s Republic of China (GB/T 261-2008, GB/T 21615-2008), European standards, and ASTM D93. It is an advanced analytical instrument primarily used to determine the closed flash point of petroleum products.

The Karl Fischer Coulomb titration method is the most reliable technique for detecting trace moisture in various substances. This method has been successfully implemented by the trace moisture titrator. Notably, the instrument operates with increased reliability and convenience, thanks to the use of advanced control circuits, a 32-bit embedded microcontroller as the core processing unit, and an embedded mini operating system. Characterized by fast analysis speed, simple operation, high precision, and strong automation, the trace moisture titrator is widely used in industries such as petroleum, chemicals, power, railways, pesticides, pharmaceuticals, and environmental protection.
