Product Description
120L 4-Gas Calibration Gas for CO, % CO₂ (2.0%), CH₄ (LEL), and O₂ Detection
This 120L calibration gas cylinder provides a stable, accurate mixture of Carbon Monoxide (CO) 25 PPM, Carbon Dioxide (CO₂) 2.0%, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 21.0% balanced in Nitrogen.
The 2.0% CO₂ concentration (20,000 ppm) supports industrial safety calibration, confined space entry, and elevated CO₂ detection environments.

Why 120L is the Efficiency Upgrade from 60L
The 120L cylinder delivers extended calibration capacity while maintaining manageable portability, making it ideal for teams that need more runtime without moving to bulk 680L cylinders.
2.0% CO₂ Calibration for Higher Detection Ranges
With percentage-level CO₂ (2.0%), this mixture ensures detectors respond accurately in higher concentration environments, where ppm-level gases are not sufficient.
Why Buyers Choose 120L Calibration Gas
- Fewer cylinder replacements vs smaller sizes
- Balanced portability + runtime efficiency
- Ideal for field teams and centralized calibration setups
- Supports consistent calibration across multiple devices
