Magnesium Hardness Checker® HC - HI719
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.
*Note: This checker is not suitable for use with saltwater (marine) aquariums.
The HI719 Checker®HC (Handheld Colorimeter) is a simple, accurate, and cost effective way to measure magnesium hardness. Designed as a more accurate alternative to chemical test kits, the HI719 provides quick, accurate results in four easy steps
- Easier to use and more accurate than chemical test kits
- Dedicated to a single parameter
- Small size, big convenience
- Ideal for: Water quality, Environmental, Plating, Education
