Product Description
4-Gas Calibration Gas for Multi-Gas Detector Calibration (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is designed for verifying the accuracy and response of portable multi-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 test multiple detector sensor channels during bump testing and scheduled calibration procedures.
Supplied in a 120L aluminum cylinder pressurized to 1050 PSI, this high-capacity calibration gas cylinder is ideal for facilities maintaining larger fleets of gas detectors or performing routine calibration across multiple instruments.
The C-10 valve connection ensures compatibility with standard calibration regulators used with most portable gas detection instruments.
