Product Description
4-Gas Calibration Gas for Portable Multi-Gas Detector Calibration (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is designed to verify the response accuracy of portable gas detectors used to monitor toxic gases, combustible gases, and oxygen concentrations in industrial safety environments.
The mixture contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 100 PPM, Methane (CH₄) 1.45% (58% LEL Pentane Equivalent), and Oxygen (O₂) 15.0%, 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 66L aluminum cylinder pressurized to 1150 PSI, this calibration gas cylinder offers a portable yet durable solution for technicians maintaining gas detection equipment in the field.
The C-10 valve connection ensures compatibility with standard calibration regulators used with most portable gas detection instruments.
