Brief Introduction:
• TH2821 Series is the first portable LCR meter with MPU control in China. It can measure following 6 parameters: L, C, R, |Z|, D and Q with 0.3% basic accuracy, 3 meas/sec measurement rate and suitable 4 Bins comparator. The use of complete 4-terminal measurement makes it possible for accurate low dissipation capacitor measurement with a portable meter. This portable meter can be used instead of a general purpose low frequency LCR meter with its good performance. With the battery and external power supply, TH2821 Series is ideal for field and portable applications such as fixed place component inspection and immediate measurement by buyers and maintenance personnel.
