Our calcium hardness checker offers you a middle ground between advanced instrumentation and your typical chemical test kit. Standard test kits have limited accuracy since they rely upon the human eye to match colors. Our handheld colorimeter eliminates the hassle of matching to a color chart by providing a direct calcium hardness result digitally.
