Guest guest Posted December 29, 2004 Report Share Posted December 29, 2004 > http://scientificsonline.com/product.asp_Q_pn_E_3081435 I got one of these for Christmas, from Edmund's scientific supply. Great idea! It's a little digital thingie you put in liquid and it tells you the exact PH. Only thing is, you have to soak it for 2 hours in water before using it. They sell a " storage solution " you can put in the cap, which looks like water with some preservative in it. Heidi Jean Quote Link to comment Share on other sites More sharing options...
