■ With its advanced impedance test technology, Tonghui has launched TH2822 series handheld LCR meters. This series currently possess the most powerful  functions and outstanding performance  in  this industry comparable with bench LCR meters. Meanwhile  it  is  the achievement of Tonghui after years of efforts and  research  in  the passive-component testing ield. TH2822 series apply the ultra-low power consumption design and high density SMD assembly  techniques and can simultaneously display primary and secondary parameters on a LCD display with backlight. The dual-color shell  is gorgeously once shaped; and  functions are easy  to operate. The  test  frequency  is up  to 100 kHz,  the  readings of primary parameter 40,000 counts and  the  resolution of dissipation factor 0.0,001. Accurate and convenient measurements of passive-components can be achieved in different occasions for a long time. With USB  interface, TH2822 series can conveniently communicate with a PC and be  remotely controlled by a PC.  In order  to satisfy the  increasing  test  requirements  for SMD and balance  the different needs  for performance and price,  two  types of 4-terminal Kelvin  test tweezers: TH26009C and TH26029C are optional for users’ choice.
