Product Description
4-Gas Calibration Gas for Portable Multi-Gas Detector Testing (H₂S / CO / CH₄ / O₂)
This 4-gas calibration mixture is used for verifying the accuracy and response of portable multi-gas detectors used in industrial safety, confined space monitoring, and environmental hazard detection programs.
The certified blend contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 50 PPM, Methane (CH₄) 1.62% (50% LEL LPG equivalent), and Oxygen (O₂) 18.0%, balanced with nitrogen. These concentrations are widely used for calibration and functional bump testing of multi-gas monitoring instruments.
The gas is supplied in a 116L aluminum calibration cylinder pressurized to 1000 PSI, providing a higher-capacity calibration solution suitable for facilities that regularly service multiple gas detection instruments or conduct scheduled calibration programs.
The C-10 valve connection supports compatibility with commonly used calibration regulators designed for portable gas detector maintenance.
