Review on 🔋 Apera Instruments AI312 2-00-16-00 Replaceable by Issac Smart

I had to use one of these to test the finish of the contents in a building destroyed by children who had acidic fire extinguisher particles everywhere sprayed space. I tried pH test strips for the first approach, but I don't trust my ability to adjust the pH with them. I used 5 drops of distilled water, a one minute wait, and this sensor and was able to get fairly consistent quantitative readings. The device was fairly easy to calibrate and use. The only thing I would add is that I wish it came with an extra pack of KCL salt so you can make more of your own soaking solution. Also, I'll probably buy a glass probe sensor to use in my aquariums. Absolutely worth the money.
