I do not think of a watt meter as an absolute or precision tool it is about trending data and close enough at best. We have far more accurate tools than "the watt meter"!
I totally agree with this post. Harbor Freight is defiantly a Home Owner store and if it weren't for them I wouldn't have got as much done at my place and figured if I found I used the tool a lot I could replace it with a better quality if it broke. If your the kind of guy who thinks you have to have Top Shelf of everything you better have deep pockets or you won't get anything done. Like one old boss said Poor Folks have Poor Ways.A tool from Harbor Fright is probably good enough for use a few weekends a year. And a pro who uses that same tool every day probably chooses one with a longer service life. A wattmeter is a wattmeter. If it's a proper design and calibrated, what's the difference? Naturally the difference between "passive" and "active" peak reading probably amounts to no more than ten percent difference in accuracy. There's not a receiver on the earth that can hear a ten percent power difference.
If you need a rugged and tough tool, the Ridgid brand was a go-to for years, but expensive. And if you want a cheap tool that's good enough, there's Horrible Fright.
Just choices. The right tool for the job depends on the nature of the job.
