Product Description
Hydrogen Sulfide (H₂S) 10 PPM / Carbon Monoxide (CO) 35 PPM / Methane (CH₄) 0.5% (10% LEL) / Oxygen (O₂) 18.0% Calibration Gas – 120L Cylinder
Accurate gas detection is critical for worker safety in hazardous environments. This 4-gas calibration mixture combines Hydrogen Sulfide, Carbon Monoxide, Methane, and Oxygen in concentrations commonly used to calibrate and bump test portable multi-gas detectors used in industrial safety programs.
The 120L aluminum calibration cylinder provides extended service life compared to smaller disposable cylinders, making it ideal for routine detector maintenance programs, field service technicians, and facilities performing frequent calibrations.
