pH test

pH test
I notice that wagner sells pH test with distilled water. I thought it was important to use deionized water? As distilled can still carry a charge that can throw off a pH test.

RE: pH test
From ASTM F710:
5.3.1 To test for pH at the surface of a concrete slab, use wide range pH paper, its associated pH chart, and distilled or deionized water. Place several drops of water on a clean surface of concrete, forming a puddle approximately 1 in. (25 mm) in diameter.

From Wagner:
Both de-ionization and distillation processes remove ions from the water and produce "pure water". De-ionization processes can leave bacteria in water. Distillation leaves pure water. In terms of quality, distilled water is better. The standard calls for using either.

Hope this helps you, eaadams.
