Product Description
4-Gas Calibration Gas for Portable Multi-Gas Detector Verification (H₂S / CO / CH₄ / O₂)
This four-component calibration gas mixture is designed for testing the response accuracy of portable multi-gas detectors used to monitor hazardous atmospheres in industrial 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 toxic gas, combustible gas, and oxygen channels during calibration procedures and bump testing.
Supplied in a 66L aluminum cylinder pressurized to 1150 PSI, this calibration gas provides a portable and efficient solution for technicians performing routine detector maintenance in the field or within facility safety programs.
The C-10 valve connection ensures compatibility with commonly used calibration regulators designed for portable gas detection instruments.
