The company has more than 180 employees. More than 70% have college education or above. R&D personnel takes up more than 25% of total employees, and annual R&D investment exceeds 10% of company’s annual revenue. For the past more than 20 years, Tonghui has been devoting itself to the research and development of electronic measurement instruments. Bearing the faith of technology first, we are struggling to promote the development of domestic measurement instruments and minimize the distance with the world advanced instruments. The company establishes “Changzhou electronic component measuring instrument engineering research center”, which has undertaken the ministry/province/city/district science and technology project for many times, and won the provincial/city science and technology progress award for many times. As a result of years of effort, Tonghui has grown to be a well-known brand in electronic instrument industry.
