Good Morning. This is the 2nd (cheap) ph pen I've bought. I've calibrated correctly a few times. Still seem fucked. I threw one in the trash. Now the other seems way off. I'm using the drops for now to be sure. Anyhow, I got paid today. What is the best P.H. tester? I will spend 100 or more if a good one. Dont want too. Lol. But I will, to get correct readings. Thx. For the advice.
