Review on 🧪 Apera Instruments Premium-Series Food pH Pocket Tester Kit with Swiss Spear pH Electrode, ±0.01 pH Accuracy, -2.00-16.00 pH Range (AI313) by Francisco Yim

I'm a baker and I have this probe to easily measure the pH of my starter cultures and doughs. Just stick the spear into the dough and you'll get instant and stable readings. Calibration is easy enough with the included buffers and instructions. It also compensates for pH based on temperature and displays that value as well, although that value is slower to stabilize (especially if you're used to Thermapen). But it doesn't matter. It also has a backlight for easy reading. Here are the cons of this meter: The tip must always be in the KCl solution when not in use (like most pH meters). This means that the sensor must be stored vertically and stored horizontally in the case. I really wish they would design a vertical case for this purpose. So I have to store the sensor outside of the case. Once I accidentally hit him and he fell to the ground and the batteries fell out. The battery connector plate was slightly damaged so that it no longer snaps into place. It still works with a tight fitting lid, but this could still have been avoided if they had a case to store the probe properly upright. The amount of KCl solution included is a joke. Seriously, for a $200 counter they could have given a little more! But I still love this counter and it makes me a better informed baker. I'm also a biochemist and I haven't seen a better spear counter for the price.
