HI!

Im planning to buy ph meter and need some help. Can someone suggest a good ph meter? I need to measure the ph of shampoos and palsams, also lotions.

I have searched and found these, but i cant decide

I wish I could be more helpful. I bought a pH meter and I've never used it :?

Do you go by the zap test Lindy? I have also been considering a ph meter.

I do - I find it works well and I've only had a few that actually zapped... It's gotten to the point that I only zap test if there is something odd about the soap...
