Product Description
Refillable Quad Gas Calibration Mixture for Portable Gas Detectors
This 4-gas calibration mixture contains Hydrogen Sulfide (H₂S) 25 ppm, Carbon Monoxide (CO) 50 ppm, Methane (CH₄) 1.25% (25% LEL), and Oxygen (O₂) 18.0% balanced with Nitrogen.
The mixture is designed for calibration and bump testing of portable multi-gas detectors used to monitor toxic gases, combustible gases and oxygen levels in industrial safety environments.
Supplied in a 44L refillable aluminum cylinder pressurized to 750 PSI with a C-10 valve, this cylinder provides a reusable calibration gas solution for facilities performing routine gas detector maintenance.

Typical Applications
• Portable gas detector calibration
• Multi-gas monitor bump testing
• Confined space safety monitoring
• Industrial hygiene compliance testing
• Gas detector sensor verification
Routine calibration ensures reliable detector response to hydrogen sulfide exposure, carbon monoxide hazards, combustible gas concentrations and oxygen level changes.
