Brief Introduction
■ Tonghui TH2821B is the first handheld LCR digital bridge in China. It can measure six basic parameters: inductance L, capacitance C, resistance R, impedance Z, loss factor D and quality factor Q. It is a simplified version of TH2821A, the frequency is as low as 1KHz, there is no sorting function, and it is cost-effective. As a result of the complete five-terminal measurement method, it solves the problem of accurate measurement of series equivalent resistance and small loss capacitors that other handheld LCR meters cannot solve. This product can completely replace the general low-frequency desktop LCR meter. Due to the two power supply modes of battery and external power supply, it can not only adapt to the detection of components in fixed occasions, but also can be carried with you to meet the on-site testing requirements of procurement and maintenance personnel.
