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 HI720 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 HI720 provides quick, accurate results in four easy steps.
