A very informative video covering all important aspect of pH measuring. Hope to see more videos like this in the future, perhaps covering different parameters such as dissolved oxygen or water ammonia level measurements.
I got the Hanna ph pocket tester but I still can’t use it as it never goes to zero when I put it on,it keeps reading continuously even when I haven’t dipped it in any solution pls help
it shouldn't go to zero when you turn it on; if it did then that would mean something extremely acidic is on the end of your probe. If you are storing it in a solution, when not in use; it is just reading the pH of that solution. Just rinse it off with RO or DI water and then use it on what you are wanting to test.
