Measures Vinyl Chloride with a Range of 0.1 to 6.6 ppm.

• Measuring Range:
  • 0.1 to 0.2 ppm, 0.2 to 3.0 ppm, 3.0 to 6.6 ppm
  • Pump Strokes: 4, 2, 1
  • Correction Factor: 1/2, 1, 2.2
  • Sampling Time: 1.5 minutes per pump stroke
  • Changes from Yellow to Reddish Brown
  • 2 Year Shelf Life (in the refrigerator)
  • Reaction Principle:
    • CH₂:CHCl + Cr⁶⁺ + H₂SO₄ → HCl
    • HCl + Base → Chloride
