Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
With its profound technical accumulation in the field of impedance testing and extensive market research, Tonghui Electronics has launched a DC impedance tester with touch function and color LCD display - TH2515 series DC resistance tester. Its high performance, convenient operation and exquisite appearance are enough to compare with the cutting-edge products in the market.TH2515 series DC resistance tester adopts the current mainstream 32bits CPU and high-density SMD mounting process, 24-bit color 4.3-inch color LCD with touch function, refreshing interface and convenient operation; the highest resistance measurement accuracy of 0.01% and the minimum resistance resolution of 0.1uΩ are among the best in China. Minimum resistance resolution in the country's first, which is suitable for relay contact resistance, connector plug resistance, wire resistance, printed circuit board and welding hole resistance; well eliminate the potential error caused by the impact of thermoelectric contact on the components under test; temperature compensation and temperature conversion function to eliminate the impact of ambient temperature on the test work; out-of-phase voltage compensation function can effectively eliminate the measured parts of their own electric potential and contact potential difference; its super-resistance measurement accuracy and 0.01% is the first in the country. The TH2515 series provides almost all the mainstream interface functions, which can be conveniently used with PC for data communication and remote control.
