Model TH2030, an ultra-precise phase and frequency measuring instrument, is the first 8 digits phase meter in the world.

Accurately measure AC voltage, current and frequency. Dual channel voltage measurement loop, used for measuring the phase between voltage and current (U-I), voltage and voltage (U-U). The optimal accuracy of phase measurement is up to ±0.3 mdeg.

Meet the requirements of JJG 440-2008 Verification Regulation of Industry Frequency Single-Phase Phase Meter.


As a reference meter for high-precision phase and frequency measurement with maximum 8 digits display.

● Calibrate the phase and frequency of AC standard source.

● Detect various working phase meters and frequency meters in power system.


● Input range of AC voltage is from 10 mV to 600 V, AC current is from 0.1 mA to 12 A.

● Input range of frequency is from 5.0000000 Hz to 10.000000 kHz, the accuracy is up to ±2 ppm.
