Needs a lot of work!
This article needs to be extensively reworked and written in the same fashion as other Wikipedia articles. It reads like the instructions you would give a group of grade-school aged children on how to use a pH meter, rather than an encyclopedia entry. Where is the discussion on how it works, the theory/calculations, and similarities to instruments used to measure other ions, dissolved oxygen and/or redox????
Pleas see Wikipedia guidelines on how to write an article. — Preceding unsigned comment added by 75.73.1.89 (talk) 09:08, 19 April 2014 (UTC)
Agreed!
I'm trying to research the function of various transducers for an assignment. This article contains NO useful information about PH meters or how they function. I don't need a care guide for a meter or how to build one, I need to know HOW IT WORKS... like how OTHER articles on wikipedia are! --Cmw328i (talk) 08:30, 24 April 2014 (UTC)
Updated and expanded July, 2007
I fleshed out the descriptions and added enough info so the topic can stand on its own now... Mondy
Note made on Aug 2009. It is incorrect to say that pH meter electrodes are stored in solution of pH 3. Typical pH meter storage solutions are jus tunder pH 7 and contain KCl as well. —Preceding unsigned comment added by 128.100.134.71 (talk) 19:33, 20 August 2009 (UTC)
Note made on July 2010. It appears to me that there are errors regarding the statements of voltage output of a pH sensor. In my experience: Acid pH produces positive sensor voltage, and base has negative. If I am correct, then the equation is also incorrect: the equation would be: (Vin * -17) + 7 = Vout. I recommend calling a pH sensor manuf. to confirm. The application note (LMC6001, pg. 10) also supports this view. 69.108.77.182 (talk) 03:20, 7 July 2010 (UTC)
Pic?
We should have a picture of the meter chris 21:45, 10 November 2006 (UTC)
Update External Link?
I would like to update the external link to the National Historic Chemical Landmarks (NHCL) resource about this topic. I am the program coordinator of the NHCL program, and the page that is referenced has been replaced with http://portal.acs.org/portal/PublicWebSite/education/whatischemistry/landmarks/beckman/index.htm. May I make this change to the two citations (under Reference #2 and "External Links" section, which are the same links)? KLindblom (talk) 17:11, 2 March 2012 (UTC)
