REED Instruments R5090 Power Meter

Seems to be accurate. I bought this unit because it was well reviewed and is produced by reputable company — but why doesn’t the display have a backlight? Any lcd needs a backlight to make it easier to read. In a typical room, the display is unreadable unless you shine a light on the meter. This watt meter costs more than the typical meter. Had I known it didn’t have a backlit display I would have bought a different model.

I like this unit. It monitors current and wattage. It also provides incoming voltage, frequency and cost. I do not have much use for the cost function but have been using this unit to monitor a cluster of plugs for a computer and various accessories.

Plugged it in, messed with the settings for a minute or two, and then was up and running getting the Wh that a mission critical device used overnight. Love it. Only bad thing is that it's slightly more expensive than its comparable items, but for a device that actually works, I'll take it.

Does what the other brands do for 2x-3x the price

Seems to be accurate (given my limited testing abilities). Has PF display and correction which not all units do, but which is critical for accurate energy usage display. UL listed and quality built unlike most of the other garbage out there.
