Product Description
221L High-Capacity LEL Calibration Gas – Methane (2.5% / 50% LEL) with Ethane (500 PPM)
This Methane (CH₄) and Ethane (C₂H₆) calibration gas mixture is designed for high-capacity LEL calibration and hydrocarbon response testing, combining 2.5% Methane (50% LEL equivalent) with 500 PPM Ethane.
Balanced in air, this mixture delivers accurate combustible gas detector calibration under real-world conditions, making it ideal for catalytic bead sensors and industrial monitoring systems.
The 221-liter steel cylinder provides a scaling solution for operations that require more capacity than standard cylinders, supporting multi-device calibration workflows and extended service intervals.
