PF109 type power frequency electrical parameter measuring instrumentDetailed product description：

The PF109 power frequency electrical parameter measuring instrument can simultaneously measure three-phase voltage, three-phase current, three-phase active power, three-phase reactive power, total added power, phase, power factor, and frequency. Standard measurement of electrical energy can be achieved through unique digital/frequency conversion technology. This product adopts plasma display with RS232 interface, which can easily form an automatic measurement system. It has a wide range of voltage and current measurement, and the voltage range can be automatically switched.. It is currently one of the advanced instruments for measuring comprehensive performance of power frequency electrical parameters, and can be widely used in power departments, metrology departments, and laboratories as a 0.05 level and 0.1 level standard.
