Weifang Huaguang Electronic Instrument Co., Ltd. is a provincial-level high-tech enterprise and a recipient of the National Innovation Fund project. A joint-stock enterprise established through the restructuring of the original Weifang No.53 Factory, Weifang Computer Company, and Weifang Huaguang Electroacoustic Instrument Co., Ltd., specializing in the production of electronic measuring instruments, meters, petroleum measurement and control systems, optical electromechanical integrated equipment, etc. With a history of nearly fifty years, we have established the renowned "Huaguang" brand both domestically and internationally. The company is a high-tech joint-stock enterprise supported by national science and technology development policies, and has been listed on the Qilu Equity Exchange (code 302363). The company has strong technical strength and adheres to the path of technological innovation, management innovation, and system innovation. The company has a high-quality team of technology production personnel, advanced process equipment, a complete quality assurance system, independent research and development production capabilities, and widely absorbs suggestions from users and adopts new technologies and materials at home and abroad. It has successfully developed a new generation of multimeter calibrators, multifunctional calibrators, AC/DC standard sources and other products. Pursuing perfect quality and advocating new concepts, we have achieved remarkable results and promoted the upgrading of domestic metrology and testing equipment. The main products include HG/DO30 series digital multimeter calibrators, multifunctional calibrators, multifunctional standard sources, and electric energy meter inspection devices that have influence in metrology and quality inspection institutions; HG/CY series welding machine on-site calibration instrument; We also produce intelligent comprehensive measurement and control systems for oil storage tanks used in the petroleum industry; Computer photoelectric weft knitting machines widely used in the textile printing and dyeing industry; There are dozens of types of instruments and equipment, including digital program-controlled user switches, applied by various sectors of the community. The company has been jointly developing popular petrochemical electronic measuring instruments such as crude oil water content monitoring instrument and oil-water interface instrument with East China University of Petroleum located in Dongying since 1985. The new generation GZC-1 intelligent comprehensive measurement and control system for oil storage tanks has obtained a national invention patent. The promotion of this system has changed the history of oil detection personnel climbing oil tanks to detect parameters, and achieved computer-controlled automatic and accurate measurement of various indicators such as liquid level, oil-water interface, sludge thickness, moisture content, temperature, and storage volume of the medium in the oil storage tank. The company has long been committed to the development and popularization of fully automatic computerized photoelectric weft knitting machines. The latest HGZW-III weft knitting machine integrates high performance and high reliability, and adopts swing type rotating photoelectric scanning detection, with no blind spots in detection. The weft yarn condition is displayed and recorded in real-time on a LCD screen, with automatic tracking of fabric speed, PID proportional control, and ultra-low speed blocking alarm functions. It is an ideal equipment for the textile printing and dyeing industry. The product sells well throughout the country and has entered the international market, and is recommended by the National Metrology Association. Over the years, it has been recognized and favored by users. We adhere to the corporate philosophy of "quality wins, integrity-based"; Adhering to the entrepreneurial philosophy of "quality first, excellent service, customer first, and pursuit of better", we work together with colleagues from all walks of life to create brilliance.
