20ppm H2S, 60ppm C0, 15%O2, 1.45% vol. CH4, 34L | MSA

Concept Controls Gas Mixture – Model 34L-428-20

Gas Composition (Nominal Concentrations):

• Hydrogen Sulfide (H?S): 20 ppm
  • A highly toxic and corrosive gas, present at trace levels for calibration or process testing.
• Carbon Monoxide (CO): 60 ppm
  • Toxic gas used in small controlled concentrations for sensor calibration.
• Oxygen (O?): 15% vol.
  • Provides a controlled oxidizing environment.
• Methane (CH?): 1.45% vol.
  • Flammable hydrocarbon at low concentration, used for testing or calibration of gas detection systems.

Container Volume: 34 liters

Intended Use:

• Calibration of gas detection and monitoring equipment.
• Laboratory analysis and simulation of industrial process gases.
• Safety and sensor performance testing in controlled environments.

Special Features:

• High accuracy: Each component is precisely blended to ensure reliable, repeatable results.
• Certified mixture: Produced under strict quality control standards, traceable to international calibration standards.
• Safe handling: Low concentrations of toxic and flammable gases allow for controlled laboratory use under proper safety conditions.

Storage & Handling:

• Store in a cool, dry, well-ventilated area.
• Avoid heat, sparks, open flames, and oxidizing agents.
• Use appropriate regulators and tubing rated for flammable/toxic gases.

Compliance & Standards:

• Manufactured to meet ISO 6142 and relevant ASTM standards for calibration gases.
• Can be used in environments requiring precise gas concentration simulations.

Notes:

• This mixture contains H?S and CO, both highly toxic, even at ppm levels—use only with adequate ventilation and gas detection measures.
• Methane presence creates a flammable hazard—avoid ignition sources.
