Product Description
4-Gas Calibration Gas for Portable Multi-Gas Detector Calibration (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is designed for verifying the accuracy of portable gas detection instruments used to monitor toxic gases, combustible gases, and oxygen levels in industrial environments.
The blend contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 20 PPM, Methane (CH₄) 1.5% (30% LEL), and Oxygen (O₂) 20.9%, balanced with nitrogen. These concentrations allow technicians to confirm sensor response across multiple gas channels during bump testing and scheduled calibration procedures.
Supplied in a 120L aluminum cylinder pressurized to 1050 PSI, this calibration gas provides extended capacity for facilities performing frequent calibration of portable gas detectors.
The C-10 valve connection ensures compatibility with standard calibration regulators used with most portable gas monitoring instruments.
