220V Kill-A-Watt? - Found! - Data Center, Colocation, Cloud Computing, Storage, Dedicated Servers Forums

I find P3 International's Kill-A-Watt meter a very handy and inexpensive way to measure a given server's electrical demand. Does anyone know of a similar device that does 220V?

Found a couple myself, in case anyone is interested. I have ordered a Smart Watt to use as a portable device for field and bench measurements, but either could also be used to add permanent metering to an unmetered rack PDU, power strip or individual device.

Smart Watt - Available in 120V and 208-240 versions with NEMA or IEC connectors. This is also a watt-hour meter, which can be used to gather data on cumulative energy usage.

MeterReader - Also has several connector options and a rackmountable panel for its LCD readout.

I think the SmartWatt was around $150, plus $40 for a USB adapter. The MeterReader was over $200, last time I checked.
