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)[reply]

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)[reply]

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)[reply]

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)[reply]

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)[reply]
