It normally sells for $25, but CT has it on sale a couple of times a year for < $20 if you can wait.

The UPM unit does record both the amount of time it has been on and the amount of power consumed. It will convert that to $ if you enter a rate. Just leave it on long enough to average out for appliances that cycle on/off. What more do you need?pauldryan wrote: ↑May 4th, 2010 11:23 amI've got the UPM version from Canadian Tire but have noticed that to properly calculate your actual consumption rates it is extremely important to manually write down the time/date that you install the unit in-line. That's because things like fridges, freezers, water coolers, etc cycle on and off and frequently don't draw any measureable power.
The UPM device will calculate the consumption rate and cost (presuming you input the rate to the device - $.15 kwh with Ontario One) but that's based upon actual running time. In a 24 hour period my freezer runs only 6 hours so to accurately project the monthly cost, one must carefully record the real metered time. If you're not using a straight forward 24 hour measured cycle, the math gets complicated.
Does anyone know if the "Kill-a-Watt" unit does this calculation automatically within the unit based upon the time it has been placed in-line? Does this unit have an on-off switch to save the batteries since the UPM doesn't and when not in use just sits there draining down the pair of "watch batteries".
