• 3 Year Shelf Life
• Reaction Principle:
• • CH2:CHCN + Cr6+ + H2SO4 → HCN
  • 2HCN + HgCl2 → 2HCl
  • HCl + Base → Chloride
• Store the tubes at a cool and dark place

• On-site measurements can be performed easily by anybody, anytime and anywhere, in a short time
• Easy-to-check direct reading possible due to calibrated scale directly printed on the tube
• An extensive measuring range can be obtained by adjusting the sampling volume
• In order to assure high precision, each production lot is tested and calibrated independently, Each detector tube has its own quality control number printed on the tube
• Long shelf-life with excellent long-term stability
