Easy to use and great results

Over the years, I've used a lot of simple pH meters. This is by far the best. It's very fast and easy to set up and calibrate, and the probes we use (primatrode) go on for years. The competition probes didn't last long in our labs, maybe a couple of weeks. I've got some of the Metrohm ones reaching their six-month point right now. We're going to stick with these for several years.
