F fcotton@iname.com Active Member Feb 17, 2009 #1 I was looking on Ebay at Pen type PH meters in the $20-$30 dollar range form china - either direct or via Australia. Does anyone have experience with these. It would be to replace PH test solution.

Resident Kush Well-Known Member Feb 17, 2009 #2 great investment, those tabs are annoying. Make sure you calibrate it at least once a month. buy test solution #4 and #7

herbose Well-Known Member Feb 17, 2009 #3 I had one and could never get it calibrated right. Then I spent $60 for one that works great and is easy to calibrate. Just my experience.

Resident Kush Well-Known Member Feb 17, 2009 #4 ya herbs right, go with a more expensive one, I believe mine was closer to a hundred bucks
ideit Well-Known Member Feb 17, 2009 #5 I had a cheap one, I'd calibrate it then it would tell me my tap water had a ph of 5.2 a week later. It doesn't even turn on now...

herbose Well-Known Member Feb 17, 2009 #6 This is what I use, calibrates itself. I hate those little screws on the back of the cheap ones. Auto shut off too, no wasted batteries. http://www.kalyx.com/store/proddetail.cfm/ItemID/768106/CategoryID/12000/SubCatID/2835/file.htm
