do i need some SPECIAl ph meter, or will this one do? http://cgi.ebay.com/NEW-Digital-Mini...QQcmdZViewItem
Perfect, but if you are low on cash, k marts sell a cheap 9 dolar one but i dotn know how well they work. i wonder why walmart doesnt sell them or jiffy cubes.. or maybe its jsut my two walmarts.
i can't find one on kmart.com. I'd love to save money, though! I'm also looking for a small temperature monitor, and fan controller too
Dont skimp to much on meters.our meters are very important!!! don't forget to buy some reference solution as well youl nYeed 7.0 and 4.0 .check the meter because some meters only call for the 7.0 reference solution
