Description

Short-term Dräger-Tube for the detection of phosphine, used in applications such as fertilizer fires or fumigation.

Dräger tubes are glass vials containing a chemical reagent designed to detect and measure gas concentrations. These tubes are used with manual pumps, such as the Dräger Accuro™ bellows pump, or automatic pump systems.

  • Gas Measured: Phosphine
  • Standard Measuring Range: 0.5 to 3 ppm
  • Number of Strokes (n): 1
  • Measurement Duration: Approx. 1 min
  • Standard Deviation: ±10% to 15%
  • Color Change: Yellow to red
  • Sample Volume: 100 mL
  • Temperature Range: 2°C to 40°C
  • Humidity Limit: Max. 40 mg H2O/L
  • Reaction Principle: PH3 + HgCl2 → Hg-phosphide + HCl; HCl + pH-indicator → red reaction product
  • Cross Sensitivity: Up to 6 ppm sulfur dioxide or 15 ppm hydrogen chloride do not interfere with the reading. Higher concentrations may cause positive errors. Ammonia (>100 ppm) may cause negative errors. Arsine and hydrogen sulfide are indicated with different sensitivities. 30 ppm hydrogen cyanide does not interfere.

  1. Extension of measuring range listed is possible for some detector tubes. Call Fisher Scientific™ at 1-800-772-6733 for more information.
  2. Safety Equipment Institute (SEI) certified.
