electric meter calculator

We saw on one of the episodes a LCD hand held device and remote sensor that straps to your electric meter and calculates usage $ and KWH in real time. Can anyone provide information on where to purchase these?

Thanks in advance

I'm not sure if this is exactly what you mean...

This unit plugs into an outlet and then you plug in whatever electric device you wish to measure. You can use an extension cord for easier reading but it will also remember the measurements until you manually clear it.

It measures several things including voltage, elapsed time etc and will do the KWH and cost calculations by day, week, month, and year for you once you program in kwh cost from your electric bill.

It's a good way to find out how much that DVD player is costing you even when it's turned off.

My link is from the Harbor Freight site but you can get these on Amazon and lots of other stores.
