Review on π Hydrion Chart Dispenser - 5.58 pH Range by Edwin Kreps
far away when I check the same solution with the certified meter
I recently bought a certified digital pH meter because I had problems and needed to check the pH frequently. the same solution with litmus and with a digital meter, the results differed by almost 1 ph. This is terribly unacceptable when it comes to pH reading and I am getting a full refund for all 4 rolls I purchased. Don't buy this product, it's not exact, so it's the same as using a paper towel and guessing the number
