For something cheap, a Milwaukee pH600 can be had for ~$20 on eBay. Test strips (like litmus paper) are very accurate, but you need to find them in the proper range.

Edit: Don't let the probe dry out or it will be ruined.

DreadedHermie Reviewed by DreadedHermie on . PH meters I am in the market for a ph meter. I've already purchased the over the counter ones from lowes and home depot and they don't work(or i just don't know what I am doing) but I've read the instructions 100 times and tried using them 100 times and still no results. LET ME KNOW WHAT WORKS AND WHAT YOU GUYS USE!!! Thanks!:smokin: Rating: 5
