Product Description
4-Gas Calibration Gas for Portable Multi-Gas Detector Calibration (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is formulated to verify the accuracy and response of portable gas detectors used to monitor toxic gases, combustible gases, and oxygen levels in hazardous environments.
The mixture 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 response across multiple sensing channels during bump testing and scheduled calibration procedures.
Supplied in a 116L aluminum cylinder pressurized to 1000 PSI, this calibration gas provides a higher-capacity solution for facilities that routinely maintain gas detection equipment.
The C-10 valve connection allows compatibility with standard calibration regulators commonly used with portable gas monitoring instruments.
