Product Description
4-Gas Calibration Gas for Portable Multi-Gas Detector Calibration (H₂S / CO / CH₄ / O₂)
This 4-gas calibration mixture is used to verify the performance and response accuracy of portable multi-gas detectors used in confined space monitoring, industrial safety programs, and hazardous atmosphere detection.
The certified blend contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 100 PPM, Methane (CH₄) 1.62% (50% LEL LPG equivalent), and Oxygen (O₂) 18.0%, balanced with nitrogen. These concentrations are commonly used to test sensor response across multiple gas detection channels in portable multi-gas monitoring instruments.
The mixture is supplied in a 66L aluminum calibration cylinder pressurized to 1150 PSI, offering a portable yet extended-capacity calibration solution for safety technicians performing routine detector verification.
The C-10 valve connection supports compatibility with standard calibration regulators used with portable gas detection equipment.
