Product Description
11L 4 Gas Calibration Gas – 40% LEL Methane, CO, O₂ (Instant Trigger Valve)
This 11L disposable 4 gas calibration gas is designed for rapid multi-gas detector calibration, featuring 50 PPM Carbon Monoxide (CO), 2.0% Methane (40% LEL), and 20.9% Oxygen (O₂) balanced in nitrogen.
Equipped with a trigger valve, this cylinder provides instant gas release without a regulator, making it ideal for quick bump testing and immediate field validation.

Why This 11L 40% LEL Cylinder is Critical
- No regulator required — fastest deployment
- Ideal for on-the-spot calibration checks
- Ultra-portable and lightweight
- Eliminates setup time
- Perfect for technicians in motion
Trigger Valve vs Regulated Cylinders
- Trigger valve (this SKU) → instant, no setup
- CGA-600 → controlled flow
- C-10 → full calibration systems
This is for speed, not precision dosing.
40% vs 50% LEL Calibration
- 50% LEL (2.5% CH₄) → standard calibration
- 40% LEL (this SKU) → controlled, lower-range validation
