Description

Provides a reliable, cost-effective method for short-term, spot measurement of hydrogen fluoride gas concentrations.

The Dräger tube is a glass vial filled with a chemical reagent designed for the detection of hydrogen fluoride. It is used in conjunction with a Dräger gas detection pump, such as the Accuro™ pump, to measure gas concentrations through a colorimetric reaction.

  • Standard Measurement Range: 0.5 to 15 ppm
  • Measurement Time: Approximately 25 seconds
  • Number of Strokes (n): 10
  • Standard Deviation: 20% to 30%
  • Color Change: Blue-violet to yellow
  • Operating Temperature: 10°C to 40°C
  • Operating Humidity: 30% to 80%
  • Reaction Principle: HF + pH-indicator → yellow reaction product
  • Cross-Sensitivity: Mineral acids, such as hydrochloric acid or nitric acid, are also indicated. Basic gases, such as ammonia, can cause negative errors or prevent indication entirely.
