Product Description
120L Standard LEL Calibration Gas – Methane (2.5% / 50% LEL) with Ethane (500 PPM)
This Methane (CH₄) and Ethane (C₂H₆) calibration gas mixture is designed for LEL calibration and hydrocarbon response validation, combining 2.5% Methane (50% LEL equivalent) with 500 PPM Ethane.
Balanced in air, this mixture ensures accurate combustible gas detector calibration under real-world atmospheric conditions, making it ideal for catalytic bead sensors and LEL monitoring systems.
The 120-liter aluminum cylinder provides a standard high-capacity solution for routine calibration schedules, multi-instrument environments, and industrial safety compliance programs.
