With its leading impedance testing technology, Tonghui Electronics has launched the industry's most powerful, comparable to the performance of benchtop instruments, a new generation of TH2822 series of handheld LCR digital bridge, the product is the same as the company's passive components in the field of testing for many years of unremitting efforts and exploration of the crystallization.
TH2822 series handheld LCR digital bridge with ultra-low power consumption design and high-density SMD assembly process, the main and secondary parameters are displayed simultaneously with backlit LCD display, fresh and dazzling one-time molding of the two-color casing, the operation of the function is simple and clear, the test signal frequency can be up to 100kHz, the main parameters of 40,000 words readings and loss factor of 0.0001 resolution, in any place can be Long time to realize the passive components for accurate and convenient measurement.
In order to respond to the needs of different sites, multiple signal level tests have been added to the TH2822D/E, and the DCR test function has been added, with a test accuracy of 0.1%. The TH2822 series provides USB interface communication capability, which makes it easy to communicate with a PC for data communication and remote control. To meet the increasing demand for SMD device testing, users can also choose TH26009C and TH26029C two SMD four-segment Kelvin test clamps to balance the different needs of performance and price.
