Product Description
4-Gas Calibration Gas for Portable Multi-Gas Detector Calibration (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is used to verify the accuracy and response performance of portable gas detectors that monitor toxic gases, combustible gases, and oxygen concentrations in hazardous industrial environments.
The mixture contains Hydrogen Sulfide (H₂S) 20 PPM, Carbon Monoxide (CO) 60 PPM, Methane (CH₄) 1.45% (58% LEL Pentane Equivalent), and Oxygen (O₂) 15.0%, balanced with nitrogen. These concentrations allow technicians to confirm detector sensor performance during bump testing and scheduled calibration procedures.
Supplied in a 44-liter aluminum cylinder pressurized to 750 PSI, this calibration gas cylinder offers a compact solution for portable gas detector servicing in the field or at safety equipment maintenance stations.
The C-10 valve outlet ensures compatibility with standard calibration regulators used with portable gas detection equipment.
