Deionized Water HI70436M testing Perfect for controlling your RODIPerfect for the Hanna Calcium Checker! Ultra Pure deionized water that keeps your titration tests accurate and repeatable. The biggest complaint about the Hanna Calcium Checker is when the sample is diluted, if the fresh water source is not pure, it can cause irregular readings and using Hanna's Deionized Water will help prevent that from happening. The water is good for any other type of test that requires dilution of the sample before titration.
