Changzhou Tonghui Electronics Co., Ltd. was founded in 1994 and is a national high-tech enterprise integrating R&D, manufacturing and marketing. In September 2021, the company moved into a garden-style modern factory with an area of ​​45 mu and a construction area of ​​30,000 square meters. There are more than 250 employees, more than 75% have college degree or above, and R&D personnel account for more than 25% of the total number of employees. The company was listed and traded on the Selected Layer of the New Third Board on January 11, 2021, raising 150 million yuan of funds, with the stock code: 833509.

Since its establishment, the company has been committed to the research and development of electronic measurement instruments, especially in the field of precision impedance measurement, which has accumulated nearly 30 years of testing theory, testing technology and practical experience. The company follows the industry development trend and replans the development strategy of "intelligent testing, efficient testing, precise testing, and industrial interconnection" and practices the craftsmanship spirit of "professional, focused, and attentive". Based on the deep understanding of the industry development prospects and the expansion of the electronic measurement instrument industry chain, the company has further deepened its efforts in the fields of power electronic measurement instruments and complete measurement system solutions, and is committed to becoming an international advanced electronic measurement. Testing comprehensive solutions provider.

Based on its persistent pursuit of product technology and strong mission of industry progress, Tonghui continues to maintain a high level of R&D investment, and its proportion of the company's revenue has remained above 13% for a long time. At present, a strong technical research and development team has been tempered, and has accumulated rich core technical achievements in hardware testing, embedded software and algorithms, buses, system integration, industrial interconnection, etc., effectively solving the batch testing efficiency of high-end electronic components A series of technical bottlenecks such as low, poor accuracy, weak comprehensive testing capabilities, and constantly breaking foreign monopoly in terms of high frequency, high speed and high precision indicators. The company has successfully developed a 6-bit semi-desk digital multi-meter, a broadband and high-precision electronic transformer comprehensive test system, a 1MHz high-speed precision capacitor meter, a 2MHz precision impedance analyzer, a 120A high-current inductor bias current characteristic test system, and a parallel multi-channel electrical safety test Many core products with independent intellectual property rights, including instruments, 10MHz precision impedance analyzers, etc. And successfully launched a 130MHz precision impedance analyzer in 2021.

The company currently has a product line with superior performance and rich specifications: component parameter tester instruments, winding component test instruments, electrical safety test instruments, wire harness/cable test instruments, weak signal test instruments, power electronic test instruments, bench-top digital Multi-purpose meters, data collector/recordizer, automatic power supply/battery comprehensive testing system, etc. The products are widely used in scientific research, production testing and quality management in 3C consumer electronics, 5G communications, semiconductor packaging and testing, new energy vehicles, power electronics, household appliances and other fields. The company insists on using innovative solutions to help customers solve measurement problems, improve testing efficiency and product quality.

The company has built a multi-level marketing model, integrating direct sales, distribution, B2C and ODM.
