Product Description
4-Gas Calibration Gas for Multi-Gas Detector Calibration and Bump Testing (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is designed to verify the performance of portable gas detectors used to monitor toxic gases, combustible gases, and oxygen levels in hazardous industrial environments.
The mixture includes 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 validate detector sensor response during routine bump testing and scheduled calibration procedures.
Supplied in a 116-liter aluminum cylinder pressurized to 1000 PSI, this calibration gas cylinder provides extended capacity for facilities maintaining multiple gas detection instruments or performing regular calibration cycles.
The C-10 valve outlet ensures compatibility with standard calibration regulators used with portable gas detection equipment.
