The intermolecular forces form the interfacial tension or surface tension of a liquid, and the magnitude of the tension value can reflect the physical and chemical properties of the liquid and its material composition. It is one of the important indicators for evaluating product quality in related industries. The fully automatic tension tester produced by our company complies with the GB/T6541 standard and is based on the ring method (platinum ring method) to measure the surface tension (liquid gas phase interface) and interfacial tension (liquid-liquid phase interface) of various liquids. This method is widely used due to its advantages of simple operation and high accuracy. Widely used in industries such as electricity, petroleum, chemical, pharmaceutical, food, teaching, etc

The KDZD5550 series cable testing terminal is used for AC testing and measurement of partial discharge and tan δ plastic insulated medium voltage cables. These cable terminals are oil insulated.
Its main features include easy operation, short cable preparation time, and short setup time.
The cable end can be prepared far away from the testing laboratory, and the cable can be easily installed on the terminal. Under normal circumstances, the insulation oil (commercially available mineral oil) used in cables can be used at the terminal for several months before replacement or filtration is required.
The KDZL-807G fully automatic interfacial tension tester measures the surface tension of various liquids (liquid gas phase interface) and the interfacial tension between mineral oil and water (liquid-liquid phase interface).
The Wen bridge sine wave oscillator composed of high-precision and high-speed operational amplifiers has the characteristics of low distortion and easy debugging.
Detection of oleic acid values in transformers and turbines
The KDSZ-803D fully automatic oil acid value analyzer adopts the principle of neutralization method. At room temperature, the microcomputer controls the automatic completion of liquid addition, stirring, titration, and endpoint judgment.
The KDWS809G fully automatic trace moisture analyzer is an instrument that uses Karl Fischer coulometric titration to determine trace moisture in liquids, gases, and solids.
The micro moisture analyzer adopts an automatic control circuit, a 32-bit embedded microprocessor as the main control core, and is embedded in a mini operating system. This makes the instrument more reliable and convenient to use. It has the characteristics of fast analysis speed, simple operation, high accuracy, and strong automation. Widely used in sectors such as petroleum, chemical, power, railway, pesticide, medicine, and environmental protection.
The KDSR-303D fully automatic water-soluble acid tester can automatically complete functions such as heating, constant temperature, oscillation, sampling, testing, cleaning, printing, etc. according to the user's set conditions, and can measure 1-6 samples at once.
Determine the amount of water-soluble acids in oil products
The KDJJC-G insulation oil dielectric strength tester can automatically complete a series of operations such as static discharge, boosting, stirring, calculating the average value, displaying data, storing data, printing, and can also measure the temperature and humidity at that time. Oil withstand voltage cycling test can be conducted within the range of 0-100kV.
