Zibo Huakun Electronic Instrument Co., Ltd. is located in the High tech Zone of Zibo City and has been engaged in Carl for many years Theoretical research and product development of Fischer Coulomb method for trace moisture determination, liquid surface and interfacial tensiometers, and surfactants.
The DT-30 series fully automatic trace moisture analyzer is carefully designed for chemical analysts by Zibo Huakun Electronic Instrument Co., Ltd. with years of research and development experience and technical accumulation. This series of instruments strictly adopts the Karl Fischer Coulomb method, which has significant advantages such as high measurement accuracy, good repeatability, and low testing cost. It is widely used in fields such as petroleum, chemical, pharmaceutical, power, scientific research, and education, and can accurately determine trace amounts of water in various liquids, solids, and gases.
As a participant in the formulation of national metrological technical specifications, our company has been deeply involved in the drafting of the "JJG 1044-2008 Karl Fischer Coulombic Method for the Calibration of Trace Moisture Determination Instruments". The DT-305 model has been designated as the experimental verification instrument for this regulation, fully reflecting the authority and reliability of the product. In addition, the academic paper "Principle and Application Range of Karl Fischer Coulomb Method Micro water Meter" published by the company's technical personnel has been selected for the Proceedings of the National Science and Technology Conference of the China Association for Science and Technology, demonstrating its profound technical expertise and industry contribution.
The article "Principle and Application Range of Karl Fischer Coulombic Moisture Analyzer" co authored by Shandong Institute of Metrology and our company was selected for the Kexi Academic Annual Conference Proceedings "Enterprise Metrology Testing and Quality Management". This article is an early professional paper in the field of physical and chemical analysis that systematically elaborates on the Karl Fischer Coulomb method moisture analyzer. The article takes a series of trace moisture measuring instruments as the main line, starting from product and method standards, moisture measurement classification, instrument principles, and their specific applications in multiple disciplines and production fields. It deeply explores the interference mechanism of substances on Karl Fischer reagents, the principle of similar solubility, and summarizes the key processes and experiences in experimental analysis. The principle and application of this method and instrument are systematically introduced. This article combines science popularization and professionalism, providing guidance for moisture determination in the fields of electricity, chemical engineering, medicine, and scientific research. It can also serve as an important reference for compiling relevant testing documents.
In addition, the article "Study on the Coulombic Method for Determining Moisture in Ketones" jointly published by Shandong Institute of Metrology and Zibo Institute of Metrology and our company was published in "Chemical Analysis Metrology". This study successfully applied the Karl Fischer Coulombic method moisture analyzer to the determination of moisture in ketone aldehyde chemicals, which has pioneering significance in methodology.
Our company's independently developed DT-102 fully automatic interfacial tension meter has obtained national patent authorization, and the instrument has won industry recognition in terms of performance and designauthorityRecognition - Li Yefeng, an expert in oil analysis for electric power in China and the director of the Oil and Gas Research Institute of Xi'an Thermal Power Research Institute of State Grid Corporation of China, and our technical personnel have jointly published a special article titled "Improvement and Testing Methods of Automatic Interface Tension Meter" in the core journal "Thermal Power Generation".
In long-term application practice, we have gradually developed a complete set of dynamic surface tension measurement methods for various surfactants, achieving an important breakthrough in the theoretical level of domestic ring tension meters. At present, the relevant formulas in national standards describe a curve relationship, and the Huakun DT-102 tension meter strictly follows this curve for equidistant multi-point calibration. Compared to some similar products that approximate the curve to a straight line for calibration, which causes testing deviation, limited range, and difficulty in stabilizing pure water calibration values in the range of 71-72mN/m, the design of the DT-102 instrument follows theoretical formulas and can be regarded as a tension instrument product that truly realizes the correct engineering application of this formula in China.
Huakun always adheres to the concept of "integrity-based, strict quality control, continuous learning, and excellent service". We welcome your inquiries and look forward to communicating with you!
