Handheld Digital LCR Meter TH2821A

TH2821A is the first portable LCR meter in China. It can measure 6 basic parameters: inductance L, capacitance C, resistance R, impedance Z, dissipation factor D and quality factor Q. It has measurement accuracy of 0.3% and 4-bin sorting. Applied complete 5-terminal measurement configuration solves problem of measurement for equivalent series resistance and capacitor with small dissipation that other portable LCR meters can’t solve. It can replace general low-frequency LCR meter. With battery external power supply, the meter is ideal for field and portable applications, such as component inspection at fixed place, and immediate measurement by buyer and maintenance personnel.
