Product Description
Sulfur Dioxide (SO₂) 10 PPM / Carbon Monoxide (CO) 50 PPM / Methane (CH₄) 2.5% (50% LEL) / Oxygen (O₂) 19.0% Calibration Gas – 60L Cylinder
Portable gas detectors must be calibrated regularly to ensure accurate detection of toxic gases, combustible atmospheres, and oxygen levels. This 4-gas calibration mixture combines Sulfur Dioxide, Carbon Monoxide, Methane, and Oxygen at concentrations commonly used for verifying the performance of industrial multi-gas monitoring instruments.
The 60L aluminum cylinder provides a reliable calibration solution for technicians performing routine bump testing and sensor calibration across field operations, industrial plants, and safety programs requiring accurate gas monitoring.
