Product Description
4-Gas Calibration Gas for Portable Multi-Gas Detector Testing (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is formulated for verifying the accuracy and response of portable gas detectors used to monitor toxic gases, combustible gases, and oxygen levels in hazardous 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 detector sensor response across multiple gas channels during bump testing and scheduled calibration procedures.
Supplied in a 66L aluminum cylinder pressurized to 1150 PSI, this calibration gas offers a practical balance of portability and capacity for technicians performing routine gas 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.
