D64 Type 0.5 Portable Electric Series Low Power Factor Watt MeterDetailed product description：

The D64 0.5 level portable electric low power factor wattmeter is a portable laboratory instrument used for precise measurement of electrical power in single-phase circuits with an AC frequency of 45-65Hz COS φ=0.2. Widely used for measuring iron loss of magnetic materials and no-load tests of motors and transformers, it can also be used as a standard table for verifying lower accuracy levels. It adopts a wire structure, anti external magnetic wire shielding, and high permeability iron nickel alloy. To prevent the instrument from being impacted and causing the tension wire to break, a sleeve type limiter is used. All features fully comply with the IEC51 international standard and the GB/T7676.3 national standard.
