I don’t know how long this will last but you can get 2 packs of 100 pH test strips for $3.95! Click the link to go right to it. I got it for $1.00 with the code N3WPROMO, see if it works for you before you buy them.
I don’t know how well they work but I placed an order and will test them out when I receive them. For $1 I figured I would try them out. From what I read on the forums the strips are a tad bit off but If you want to get into testing your mash pH without buying a pH meter then this would be the way to go.
UPDATE: After taking a few more looks at this product I don’t think they will work too well for home brewing. The strips seem to only measure from 1-14 and not in between. The best strips are these but for that price you can buy a meter.
The only reason I would have chose the strips is because I wouldn’t have to calibrate them every time I use them. I have a meter already so I will compare the cheap strips to my meter on the next brew day. Sorry folks…
