Changzhou Tonghui Electronic Co., Ltd.
Changzhou Tonghui Electronic Co. Ltd. was founded in 1994. It is a provincial high-tech enterprise integrating R&D, manufacturing and marketing. It is located in the National Development Zone – Changzhou Hi-tech Industry Development Zone with superior geographical position and beautiful natural environment. Covering a land area of 14000 m2 with construction area of 8200 m2 (A new plant with 30000 m2 land area and 30000 m2 construction area in the first phase is under construction). 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.

Impulse Winding Tester
TH2883-1
Changzhou Tonghui Electronic Co., Ltd.
TH2883 series products are newly developed impulse winding testers by Tonghui. This product line makes Tonghui as the first provider of impulse winding tester from low voltage of 30V to high voltage of 10kV, single channel to multichannel (Max.:8 channels) in this industry. The instrument adopts popular 32 bit CPU and high density SMD technology, 65k color 7-inch TFT wide display screen, bringing ease for your eyes and convenience to your operation. The minimum impulse voltage of 30V, maximum impulse voltage output of 10kV, winding test of 1uH inductance value, sampling rate of 200Msps, memory depth of 6k bytes makes your test accurately. The usage of standard sample average, application of demagnetized impulse, high bandwidth analog acquisition circuit, technology of high-fidelity corona extraction as well as the opening of non-destructive test reflect the design philosophy “customer-oriented, share the future technology with you” of Tonghui.

LCR Meter
TH2826A
Changzhou Tonghui Electronic Co., Ltd.
TH2826A is a new generation impedance test instrument and firstly in conformity with LXI standard inland. It fulfills most low-voltage parameter measurement needs for components and materials with its basic accuracy (0.1%), wide frequency range(from 20Hz to 2MHz). The instrument is widely applied in microphone, resonator, inductor, ceramic capacitor, LCD, varactor and transformer .etc to analyze electrical performance and test low-ESR capacitor and high-Q inductor. With the super high test speed, TH2826A is especially for frequency response curve analyzing of detector and piezoelectric device on auto production line. Its multiple output impedance mode can be used for different standards of inductor or transformer manufacturers.
