Hi,
found this PH meter on ebay
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=190457913630&ssPageName=STRK:MEWAX:VRI (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=190457913630&ssPageName=STRK:MEWAX:VRI)
Seem to have all the blows and whistles, including ATC for only $40. Any opinion?
Thanks!
With my two minutes of product review I would say that off-hand, this meter appears to do almost everything my 100 dollar meter does.
I guess it comes down to dependability and trustworthiness. For that cost, you could get two of these meters and use one to validate the other, or as a backup..
It also says you can get an extra electrode for $15. Would one need an extra electrode? Is that something that 'wears out' or needs to be replaced often?

Yes, most pH meters of this type have electrodes that have a limited lifespan.
The internal wire can corrode, and the glass membrane can dry out.
IMHO, it doesn't look like the electrode is capable of surface testing. Compare that to one similar to the Exstik (http://www.extech.com/instruments/product.asp?catid=69&prodid=431). That's important if you want to check the pH of the cheese right out of the press where there is very little whey to dip the electrode in.
Just a thought....

oh yeahh.. good catch.
I use that alot too.
:'( thanks you all guys, will have to pass on this one.
I also make fermented sausages so this surface metering would be useful to me.
