Product Description
4-Gas Calibration Gas for Portable Gas Detector Calibration (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is designed for verifying the response of portable gas detectors used to monitor toxic gases, combustible gases, and oxygen levels in industrial safety environments.
The mixture contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 50 PPM, Methane (CH₄) 1.45% (58% LEL Pentane Equivalent), and Oxygen (O₂) 18.0%, balanced with nitrogen. These concentrations allow technicians to check detector performance across multiple sensor channels during bump testing and scheduled calibration procedures.
Supplied in a 116L aluminum cylinder pressurized to 1000 PSI, this calibration gas cylinder provides extended capacity for facilities performing routine calibration on multiple portable gas detectors.
The C-10 valve connection ensures compatibility with common calibration regulators used with most portable gas detection instruments.
