Measuring the pH of water is critical to the health of humans and organisms, which is why water pH is measured instantly in water and wastewater treatment plants, greenhouses, fish ponds, aquariums and industrial systems.
Using pH (0-14) and (10-1) papers, the pH of aqueous solutions can be measured accurately and quickly.
Paper PH -: 14 - 0 Stripe
Paper PH -: 10 - 1 roll
Turnstile paper: blue and red
