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.

● dual channel voltage input with u-i and u-u phase measurement modes, 6 digits display.
