Calcium
Hardness Checker
The
Hanna Checker® bridges the gap between simple chemical test kits and
professional instrumentation. Chemical test kits are not very accurate and
only give 5 to 10 points resolution while professional instrumentation can
cost hundreds of dollars and can be time consuming to calibrate and
maintain. The Checker® is both accurate and affordable.
The
HI-720 Checker®HC (Handheld Colorimeter) is a simple, accurate, and cost
effective way to measure calcium. Designed as a more accurate alternative
to chemical test kits, the HI-720 provides quick, accurate results in four
easy steps:
Features
-
Easier to use and more accurate than chemical test kits
-
Dedicated to a single parameter
-
Small size, big convenience
-
Ideal for water quality, education, environmental, plating
