Product Description
66L Lower-Range LEL Calibration Gas – Methane (1.0% / 20% LEL) with Ethane (200 PPM)
This custom calibration gas mixture combines Methane (CH₄) at 1.0% (20% LEL equivalent) with Ethane (C₂H₆) at 200 PPM, designed for lower-range LEL calibration and sensitivity verification.
Balanced in air, this mixture enables accurate combustible gas detector response under real-world conditions, making it ideal for catalytic bead sensors and gas detection systems requiring precise low-level response validation.
The 66-liter aluminum cylinder provides a portable, mid-capacity solution for routine calibration, detector testing, and compliance verification.
