Details
The HN/000749 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 HN/000749 provides quick, accurate results in a few easy steps.
