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 performance of portable gas detectors used to monitor toxic gases, combustible gases, and oxygen levels in hazardous industrial environments.
The blend 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 test 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 provides a practical portable solution for routine detector maintenance and field calibration work.
The C-10 valve connection ensures compatibility with standard calibration regulators commonly used with portable gas detection instruments.
