Shijiazhuang Jiuheng Electrical Instrument Co., Ltd. integrates design, development, production, and sales services, specializing in the production of ammeters, voltmeters, frequency meters, pointer ammeters, digital ammeters, digital voltmeters, splitters, and current transformers. The company attaches great importance to the comprehensive equipment and modern talent cultivation necessary to ensure career success. The company not only has strong technical strength, first-class production equipment, first-class production processes, and exquisite production techniques, but also has high-quality employees and excellent inspection equipment. The JY series installed electric meters produced by the company have a reasonable structure, silicone oil damping, replaceable dial, and shockproof structure. They have advanced domestic level and are internationally standardized products, entering the European and Southeast Asian markets. We hope to be your ideal choice, and we will adhere to the principle of "serving customers to the greatest extent possible" to create customer satisfaction and quality. Our company has developed the latest generation of JY series digital power meters based on existing calibration instruments and standard equipment products. It is a new generation of electrical measuring instruments, mainly used for real-time measurement and indication of various electrical parameters in power lines, and for transmitting measured electricity data through 485 interfaces or analog transmission output interfaces. With high measurement accuracy, good stability, and the ability to set parameters on-site through panel buttons, it is an ideal substitute for pointer instruments. The product adopts high-performance microprocessors and applies digital signal processing technology. Through the programmable keyboard of the instrument, it is very convenient to set parameters such as transformer multiplier, upper and lower limit alarm values (or ranges), alarm switching difference, communication address and communication baud rate, variable frequency output mode and range, digital filtering mode and digital filtering coefficient of the instrument. Adopting internationally popular appearance manufacturing technology, the product has a beautiful appearance, intuitive and convenient operation, and simplifies installation and operation steps. The overall performance of the product is stable and reliable, and it has been widely used in fields such as electricity, petrochemicals, metallurgy, railways, papermaking, and medicine.
