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 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, Education, Industrial, Municipal Water
Chromium, Hexavalent Range 0 to 300 ppb Chromium, Hexavalent Resolution 1 ppb Chromium, Hexavalent Accuracy ±3 ppb ±5% of reading Chromium, Hexavalent Method adaptation of the ASTM, Manual of Water and Environmental Technology, D 1687-92, Diphenylcarbohydrazide method.
