Share 'Any recommendations for a reliable digital pH meter?'
I have a Hanna Checker digital pH meter but I think the probe is at the end of its lifespan. Before ordering a new probe, I wondered if any of you experienced folks have a preferred pH meter choice/brand?
(The API colorimetric pH test is making me wonder if I have a rare form of color blindness! I can never convince myself which color really matches.)
