Product Description
Large-Capacity Quad Gas Calibration Gas for Portable Detector Calibration
This 4-gas calibration mixture contains Hydrogen Sulfide (H₂S) 25 ppm, Carbon Monoxide (CO) 50 ppm, Methane (CH₄) 1.25% (25% LEL), and Oxygen (O₂) 18.0% balanced with Nitrogen.
The mixture is commonly used for calibration and bump testing of portable multi-gas detectors designed to monitor toxic gases, combustible gases and oxygen concentration in industrial safety environments.
Supplied in a 116L disposable aluminum cylinder pressurized to 1000 PSI with a C-10 valve, this cylinder provides a reliable calibration gas supply for facilities performing routine detector maintenance and sensor verification.
