Product Description
4-Gas Calibration Gas for Multi-Gas Detector Calibration (H₂S / CO / CH₄ / O₂)
This 4-gas calibration mixture is formulated for verifying the performance of portable multi-gas detectors used in confined space entry, industrial safety programs, and environmental hazard monitoring.
The certified blend contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 50 PPM, Methane (CH₄) 1.62% (50% LEL LPG equivalent), and Oxygen (O₂) 17.0%, balanced with nitrogen. The reduced oxygen concentration allows technicians to confirm detector response to oxygen-deficient conditions, an important safety parameter in confined spaces and hazardous work environments.
Supplied in a 116L aluminum cylinder pressurized to 1000 PSI, this calibration gas provides extended capacity for organizations performing routine instrument calibration across multiple detectors.
The C-10 valve configuration ensures compatibility with common calibration regulators used with portable gas detection equipment.
