We had great fun in the workshop making a bunch of little videos about pH, pH indicators, adjusting, testing, and everything else to do with this topic. Here’s a little 2 minute video we made showing how phenolphthalein behaves when we add an acid and reduce the pH. We took a look at pH indicators…...
I went into quite a bit of detail in this post – Acids, bases, and pH – oh my! Part four: Testing our products with pH meters – but thought I’d write up a quick reference post on how to adjust the pH of our products. If you want to reduce the pH or make…...
If you want to catch up on this series, please check out the pH & pH meters section of the blog by clicking the link. I thought I’d share a little more of the science of our pH meters with you as I found it really interesting! You don’t need to know this to test…...
You’ve met all the meters I own and have learned how they work, so let’s do a recap of the things to consider when using and storing them. If you’d like to see the rest of this series, please visit the pH & information about meters, a new section we’ve created for the blog! You can…...

I’m really enjoying having a magnetic stirrer doing all the mixing work for me so I can make other things, so let’s take a look at this new addition to my workshop! Please note, none of these are affiliate links or links from which I’ll benefit. I’m sharing where I found the things I bought,…...
Now that we’ve met all the meters I have, let’s take a look at which ones I liked and which ones I didn’t! I find it helpful to gather all my meters and test the heck out of them using the same fluids. You can see this in action in this post where I compared…...
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…...
