Product Description
60L 4 Gas Calibration Gas – 40% LEL Methane, CO, O₂ (Field Calibration Cylinder)
This 60L 4 gas calibration gas is designed for multi-gas detector calibration under standard atmospheric conditions, featuring 50 PPM Carbon Monoxide (CO), 2.0% Methane (40% LEL), and 20.9% Oxygen (O₂) balanced in nitrogen.
This mixture provides a 40% LEL methane concentration, enabling lower-range LEL sensor validation and controlled calibration scenarios where full 50% LEL testing is not required.
Gas Composition
- Carbon Monoxide (CO): 50 PPM (Standard Level)
- Methane (CH₄): 2.0% (40% LEL)

- Balance Gas: Nitrogen (N₂)
Cylinder Specifications
- Cylinder Size: 60L
- Pressure: 1000 PSI
- Valve: C-10
- Material: Aluminum
- Reactivity: Non-Reactive
Applications
- LEL sensor calibration (partial-range testing)
- Multi-gas detector validation
- Controlled methane calibration
- Routine industrial safety monitoring
- Field calibration programs
Why 40% LEL Calibration Gas Matters
- Enables lower-range LEL calibration testing
- Supports graduated sensor validation
- Provides more conservative calibration scenarios
- Useful for compliance programs requiring multi-point testing
- Complements standard 50% LEL calibration gases
40% vs 50% LEL Calibration
- 50% LEL (2.5% CH₄) → standard calibration
- 40% LEL (this SKU) → controlled / lower-range validation
Oxygen Context
- 20.9% (this SKU) → baseline atmosphere
- 19.0% → early deficiency
- 18.0% → critical
- 17.0% → severe
60L Cylinder Advantage
- More portable than 66L / 120L
- Ideal for field technicians
- Balanced runtime vs size
- Compatible with C-10 systems
