pH meters

This one has a strange way of calibrating, by using a screwdriver to alter it if it doesn’t register exactly the reading you want.  This has an all in one glass electrode. It has an accuracy of +/- 0.05 pH. It doesn’t measure temperature and doesn’t have automatic temperature compensation, so if you’re measuring a liquid...

This is the worst meter I’ve tested thus far, completely inaccurate and annoying. This has an all in one glass electrode. It has an accuracy of +/- 0.05 pH. It doesn’t measure temperature and doesn’t have automatic temperature compensation, so if you’re measuring a liquid that’s less than 20˚C and higher than 25˚C, it won’t be...

I tried this one at Windy Point Soap Making Supplies in 2017, and it was still calibrated in 2018! I can’t remember what we did out of the box, to be honest, but I think the instructions said to soak it for 2 to 3 hours in distilled water. This machine comes with three calibration...

I bought this one by accident! I put a few different meters into my Amazon cart, and figured I’d hit “save for later” before checking out, but I didn’t, and it soon ended up at my house.  This one has a glass electrode and measures pH and temperature. It measures pH 0.1 to 14, +/- 0.02...

This was the first meter I ever owned, a lovely Christmas present from my husband and mom in 2010, and it served me well for seven long years.  This meter has a glass sensor and reference tube, and the electrode can be easily replaced. It measures temperature – -9.9˚C to 99˚C or 14˚F to 212˚F, the...
