MATRIXMPM-1010 High Precision Bench Digital AC Power Meter - Voltage Current Power Factor and Frequency Meter with Upper and Lower Limit Set and Sound Light Alarm

Update : Been using it for a year now, holding up just like new, no issues. Use it for slow turn on/up of new AC powered projects. Or for testing a few of each, and data for efficiency and so on.It's on the bench as a daily driver.Only negative, could be a little shorter indepth, case wise.Front panel wise, perfect, easy to see on the bench, no front panel wasted space basically.Back outlet works great.. I'm in the USA , and the multinational outlet on the back accepts the basic Nema15 3 wire plug just fine.So far, more than accurate enough for what I use it for, while turning on new designs. Always want to watch power / current / voltage on the way up, paired with a variac.. safe.

These offer a good value for the price. They are designed around a very accurate chip and have a lot of features. I have purchased 2 of them because of the accuracy and features.

The current display used to read in mA. Tony talks about it in his YouTube review. It was wrong and now they have corrected it. That probably would have bothered me. This will be nice for watching the power consumption of devices I'm working on.

Works very well with a Variac to measure voltage and power. It does have a hum with only the device being powered without any load on the measured output.

The meter seems to work fine. The manual, however, has apparently been written by someone who THINKS they know the English language. They might just as well have written it in Chinese; that way the user might fond someone who DOES know the English language to translate it.

Power Meter&Power Factor Bench Analyzer is an exact copy of the original meter, but 5-6x more expensive! So I'm happy with the price and same performance.
