Power meter

HQ Power consumption meterWith this useful device you can monitor the energy consumption of your appliances. After you plug it into a wall outled and connect a device, it measures the consumed watts (W), results from the voltage (V) and ampere (A). You can monitor the Voltage, Frequency, power factor (PF) ) of the plug. Is ideal to keep a close eye on the consumption of your appliances.

With this power meter, I optimized and monitored my Media center / HTPC power consumption.
