The HI723 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure chromium VI. Due to its corrosion-resistant properties, hexavalent chromium plays an important part in the plating industry and cooling towers. However, due to its toxic and carcinogenic nature, chromium VI must be must be sufficiently treated prior to wastewater discharge. Designed as a more accurate alternative to chemical test kits, the HI723 provides quick, accurate results in a few easy steps.
Features at-a-glance:
- Easier to use and more accurate than chemical test kits
- Dedicated to a single parameter
- Small size, big convenience
- Ideal for: Water Quality, Plating, Industrial
