Description

Cost-effective and reliable short-term detector tube for the measurement of mercaptan gas concentrations.

Dräger short-term detector tubes for the measurement of Mercaptan gas concentrations.

  • Standard measuring range: 0.5 to 5 ppm
  • Number of strokes (n): 20
  • Measurement time: approx. 5 min.
  • Standard deviation: ±10 to 15 %
  • Color change: White → Yellow
  • Temperature range: 10°C to 40°C
  • Absolute humidity: 3 to 15 mg H2O / L
  • Reaction principle: 2 R-SH + Pd2+ → Pd(RS)2 + 2 H+
  • Cross sensitivity: Higher molecular weight alkyl mercaptans (e.g., propyl- and butylmercaptans) are indicated with approximately the same sensitivity.
  • Interfering gases: 1,000 ppm ethylene, 2,000 ppm carbon monoxide and 200 ppm hydrogen sulfide do not affect the indication.
  • Pre-layer discoloration: Hydrogen sulfide discolors the pre-layer black.

  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.
