Product Description
221L 4 Gas Calibration Gas – 50% LEL LPG / Propane Equivalent (Extended Runtime, Low-Pressure)
This 221L 4 gas calibration gas is engineered for extended-duration multi-gas detector calibration using LPG/propane equivalency, featuring 50 PPM Carbon Monoxide (CO), 1.62% Methane (CH₄) representing 50% LEL propane equivalent, and 18.0% Oxygen (O₂) balanced in nitrogen.
Configured with a CGA-165 low-pressure valve, this cylinder supports controlled, continuous gas delivery, making it ideal for multi-point validation and long-run calibration systems.
Gas Composition
- Carbon Monoxide (CO): 50 PPM

- Oxygen (O₂): 18.0% (Critical Deficiency Level)
- Balance Gas: Nitrogen (N₂)
Cylinder Specifications
- Cylinder Size: 221L
- Pressure: 250 PSI
- Valve: CGA-165 (low-pressure, continuous flow)
- Material: Steel
- Type: Disposable
- Reactivity: Non-Reactive
Applications
- Extended LPG / propane calibration programs
- Cross-sensitivity (equivalency) calibration
- Multi-point detector validation
- Continuous calibration systems
- Industrial compliance workflows
Why This 221L LPG Equivalent Cylinder Matters
- Enables propane-equivalent calibration over long durations
- Supports continuous flow setups (CGA-165)
- Reduces cylinder changeouts vs field sizes
- Ideal for multi-day or centralized calibration
- Bridges field → facility systems
Valve Context (buyer clarity)
- CGA-600 → portable regulated (short runs)
- C-10 → standard field
- CGA-165 (this SKU) → low-pressure continuous flow
