Unveiling the Journey of a Leading Electromagnetic Measurement Manufacturer in China

Part 1: Intro

    Metrology plays an important role in our society and involves all aspects of life. China currently divides metrology into ten major categories of metrology by profession, namely length measurement, thermal measurement, mechanical measurement, electromagnetic measurement, and radio measurement, time frequency measurement, ionizing radiation measurement, acoustic measurement, optical measurement and chemical measurement.

    Electromagnetic measurement has become an important method and means to support the research of measuring instruments in many fields. With the development of science and technology, various fields of modern metrology use various sensors to convert the measured into electromagnetic signals for processing. At present, it is a common phenomenon in measurement technology to convert non-electrical quantities into corresponding electric quantities for measurement, giving rise to novel demands in electromagnetic measurements.

    Starting from 1985, for more than three decades, TUNKIA has been deeply engaged in the two fields of "Electrical Measurement" and "Magnetic Measurement" and has made remarkable achievements. Now we have established a comprehensive electrical quantity transmission and traceability system, and a very complete magnetic measurement system, which can meet a variety of electromagnetic measurement needs.

Part 2: Electrical Measurement

(1) Electrical Measurement Traceability

    After years of technical accumulation in electrical measurement methods, system construction, circuit design, component testing and analysis, TUNKIA has successfully developed and produced reference-level products with an accuracy of up to 10^-4~10-⁶, which can be used in electrical metrological traceability. is applicable to all national and provincial metrology institutions, provincial electrical engineering institutes, and key scientific research laboratories. Our products have become essential tools in numerous national and provincial metrology institutions, provincial electrical research institutes, and pivotal scientific research laboratories. (See Figure 1: List of Our Key Customers)

(2) Electrical Measurement Calibration

    Based on mature and reliable traceability products, TUNKIA has designed and produced high-level measurement standards covering the fields of AC and DC electricity, electric energy, high voltage and safety regulations, medical and industrial testing, etc., which meet the electrical measurement requirements of most current measurement institutes.

Part 3: Magnetic Metrology

    The magnetic parameter measurement and calibration series products developed and produced by TUNKIA can not only be used for the calibration of magnetic measuring instruments such as Tesla meters and flux meters, but also support the traceability of basic magnetic parameters such as magnetic flux density, magnetic field strength, and magnetic flux to National Benchmarks.
