Import Double Clamp Digital Phase Meter — Buy in Bulk from Supplier in China

The double clamp digital phase meter from Guangzhou ETCR Electronic Technology Co., Ltd measures phase angles between 0 and 360 degrees with a resolution of 1 degree, while simultaneously detecting AC current from 0 to 200mA, 2A, or 10A, and AC voltage from 0 to 20V, 200V, or 500V. It features a 3-1/2 digit LCD display with a 64mm by 54mm active area and 40mm high digits, optimized for clarity under low-light conditions. The device operates on a standard 9V alkaline battery with a continuous duty life of 300 hours and includes an automatic 15-minute shutdown function to conserve power.

The instrument uses a split-core current transformer with a clamp mouth opening of 7.5mm to 40mm, allowing measurement on conductors without disconnection. Its measurement accuracy for phase is ±3 degrees, current ±1% ±2 digits, and voltage ±1.2% ±2 digits, all calibrated at 50Hz, 23°C, and 40-60% RH. The input impedance for voltage measurements is 2MΩ, and for phase comparison between U1 and U2, it is 40kΩ. These specifications align with standard industrial requirements for portable phase analyzers used in field diagnostics.

This meter is used by electrical maintenance teams, industrial technicians, and utility inspectors to verify three-phase system sequencing, transformer connection groups, and circuit reactance characteristics. Buyers typically require it for preventive maintenance, fault detection, and commissioning of low to medium voltage systems. Packaging includes the meter, two clamp probes, a 9V battery, and a protective case. Trade terms are typically FOB Guangzhou, with MOQs negotiable for bulk orders and lead times of 7 to 15 days after payment confirmation.
