Product Description
34L 4 Gas Calibration Gas – 40% LEL Methane, CO, O₂ (Portable Controlled Cylinder)
This 34L disposable 4 gas calibration gas is designed for portable 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 CGA-600 valve, this cylinder allows for regulated, controlled gas delivery, making it ideal for technicians performing precise LEL calibration in field environments.

Why This 34L 40% LEL Cylinder is Important
- Enables controlled, lower-range LEL calibration
- Provides regulated gas flow (CGA-600)
- Portable for daily technician use
- More precise than trigger valve cylinders
- Eliminates need for refillable systems
34L vs Other 40% LEL Options
- 34L (this SKU) → portable + controlled
- 60L / 66L → longer runtime
- 120L → primary field
- 680L → facility
40% vs 50% LEL Calibration
- 50% LEL (2.5% CH₄) → standard
- 40% LEL (this SKU) → lower-range / controlled validation
Valve Type Context
- CGA-600 (this SKU) → controlled, regulated flow
- Trigger valve → instant, uncontrolled
- C-10 → system-level calibration
