Summary
Watt Meter for trend of 21 Centry and new generation should be able to measure consumption power, standby power, AC and DC and be easy to use and has reasonable price. HPM-300A shows 4 factors' (Volt, Current, Watt and Frequency) measurement value on the wide LCD display at the same time and is able to measure 11 factors such as cosΘ, Wh and etc. With Clamp Sensor it is able to measure up to 1000A and also able to measure 3 Phases power by using Frondel's 2P & 3P system.
