Hanna Colorimeter
$59.95
Type
A Hanna Checker colorimeter: a pocket-size digital tester that reads one reef parameter (like alkalinity, phosphate, or calcium) far more precisely than color-card kits.
Why We Use It
Hanna Checkers take the guesswork out of testing. A digital number beats squinting at colors.
Use: Choose the checker for the parameter you need, and use the matching Hanna reagents.
