Talk:Hofmann voltameter

Inventor

The article says "invented by Friedrich Hoffmann (1660 - 1724)". I find that hard to believe, because (as far as I remember) electrolysis hadn't been discovered until around 1800 when the voltaic pile was invented. Perhaps this voltameter was invented by August Wilhelm von Hofmann (1818-1892) instead? I haven't found any evidence, but at least he has the same surname and died after the invention of the voltaic pile. Itub 20:42, 15 January 2007 (UTC)

OK, I've found several websites and books that say that the apparatus was invented by August Wilhelm von Hofmann, so I've updated the article. Itub 22:34, 15 January 2007 (UTC)

voltmeter

why does this article says that voltmeters are artifact. Ive used them many times before, in everyday life??? —Preceding unsigned comment added by 220.253.167.101 (talk) 09:42, 13 November 2008 (UTC)

Do you mean voltmeters, the electrical instruments used for measuring voltage? Those are something else. Or do you actually use the Hofmann voltameter in everyday life for measurements? --Itub (talk) 10:48, 13 November 2008 (UTC)

Did hoffmann ever use this as a measuring device?

Typicall the H voltameter or variant is used to show the 2:1 volume of H₂ and O₂ − what did Hoffman actually use this apparatus for- was it measuring current as the name suggests ( Daniell introduced this as a short form of Faradays "volta-electrometer") or was it simply to show H₂ and O₂ evolution?--Axiosaurus (talk) 10:47, 20 February 2009 (UTC)
