Product Description
4-Gas Calibration Gas for Multi-Gas Detector Maintenance (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is designed to verify the accuracy of portable multi-gas detectors used to monitor toxic gases, combustible gases, and oxygen levels in hazardous work environments.
The blend contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 50 PPM, Methane (CH₄) 1.62% (32% LEL), and Oxygen (O₂) 19.0%, balanced with nitrogen. These concentrations allow technicians to evaluate sensor response and ensure detectors are operating within proper calibration tolerances.
Supplied in a 120L aluminum cylinder pressurized to 1050 PSI, this larger-capacity cylinder is well suited for facilities that maintain multiple gas detectors or perform frequent calibration procedures.
The C-10 valve configuration ensures compatibility with standard calibration regulators used with most portable gas detection instruments.
