Product Description
4-Gas Calibration Gas for Portable Gas Detector Calibration (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 concentrations in industrial safety environments.
The mixture contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 300 PPM, Methane (CH₄) 1.45% (58% LEL Pentane Equivalent), and Oxygen (O₂) 15.0%, balanced with nitrogen. These concentrations allow technicians to test detector response across multiple sensing channels during bump testing and scheduled calibration procedures.
Supplied in a 120L aluminum cylinder pressurized to 1050 PSI, this calibration gas cylinder provides extended capacity for facilities maintaining large fleets of portable gas detectors or performing regular calibration across multiple work areas.
The C-10 valve connection ensures compatibility with standard calibration regulators commonly used with portable gas detection instruments.
