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

parameter test instrument, Winding component test instrument, Cable
harness test instrument, Electrical safety test instrument,

as well as accessories and software products. Tonghui insists to
provide users with creative solutions for more efficient
measurement and higher product quality. Tonghui has a mature
quality control system and strong product manufacturing and quality
assurance team, to ensure that the products delivered to customers
can meet the unified quality standards.

“To achieve customer satisfaction” is the principle that Tonghui
always adheres to. Over the years, Tonghui has been striving to
build a multi-level marketing system, integrating direct marketing,
agency and network sales. We have also established an after-sales
service system in more than 20 provinces and cities in China, which
helps better serve our customers, and listen to customers.
At present, the overseas market has become an important part of the
development of Tonghui business. Tonghui has gradually integrated
the technology and experience accumulated over the years into the
international competition system. It has established marketing
systems in North America, Europe, Southeast Asia and South Asia and
has achieved fruitful results, enabling high-tech products from
China to meet the needs of worldwide customers. Meanwhile, we can
continue to enrich our experience in the exchange of learning with
international counterparts. Looking forward to the future, Tonghui
