TH2821B : Portable LCR Meter (Lodestar )

LodeStar TH2821B LCR meter

TH2821B (portable LCR meter): Máy đo LCR (điện cảm, điện dung , điện trở) cầm tay tiện dụng của Lodestar, có thể đo được 6 thông số, tần số đo 100Hz, 120Hz, 1kHz

LCR meter TH2821B is the first portable LCR meter with MPU control in China. It can measure following six parameter : 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 disspation 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 is ideal for field and portable applications such as fixed place component inspection and immediate measurement by buyers and maintenance personnel.
