The HI749 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 6 must be must be sufficiently treated prior to wastewater discharge. Designed as a more accurate alternative to chemical test kits, the HI749 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, Education, Industrial, Municipal Water
