Apologies if this is in the wrong section, not sure what it counts as. I don't think it's advertising because it appears in an article on another website.
Like Victor Kayam, I was so impressed... well, I didn't buy the company but I did want to post it on EDA in case anyone is interested in this kind of AC and DC contactless voltmeter (and ammeter). If this is old news, again, my apologies...
Oops, misread something, then. The product page claims 600V DC several times as well as AC. I think it's "impressive" - maybe not the most accurate word - for being contactless, that introduces a greater degree of safety and that is always welcome with electricity.
