Product Description
4-Gas Calibration Gas for Multi-Gas Detector Verification (H₂S / CO / CH₄ / O₂)
This 4-gas calibration mixture is used to verify the accuracy and response of portable multi-gas detectors used in industrial safety programs, confined space monitoring, and hazardous environment detection.
The mixture contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 50 PPM, Methane (CH₄) 1.62% (50% LEL LPG equivalent), and Oxygen (O₂) 17.0%, balanced with nitrogen. The reduced oxygen level allows technicians to verify detector response to oxygen-deficient atmospheres, an important safety condition monitored during confined space entry and industrial maintenance operations.
Supplied in a 120L aluminum calibration cylinder pressurized to 1050 PSI, this mixture provides a higher-capacity calibration solution for facilities performing routine detector maintenance or servicing multiple gas monitoring instruments.
The C-10 valve configuration supports compatibility with common calibration regulators used with portable gas detection equipment.
