Product Description
4-Gas Calibration Gas for Portable Gas Detector Calibration (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is designed to verify the performance of portable multi-gas detectors used to monitor toxic gases, combustible gases, and oxygen levels in industrial safety environments.
The blend contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 50 PPM, Methane (CH₄) 1.5% (30% LEL), and Oxygen (O₂) 20.9%, balanced with nitrogen. These concentrations allow technicians to confirm detector sensor response across multiple channels during calibration procedures and bump testing.
Supplied in a 120L aluminum cylinder pressurized to 1050 PSI, this higher-capacity calibration gas solution is well suited for facilities that maintain multiple detectors or conduct routine calibration programs.
The C-10 valve connection ensures compatibility with standard calibration regulators used with most portable gas detection systems.
