Measuring pH of reverse osmosis's water
« on: February 05, 2019, 04:14:31 AM »
I know that it should be acidic. But when i am measuring it in 2 different bench pH meters the result is 9 (in both) and when i measure it using a pH paper strip it is around 6. Any ideas?

A pH probe needs conductivity. DiI-water or reversd osmoses water cannot measured like this. You have to add a little bit NaCl or other neutral salt to the water and measure again.
