Product Description
66L 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 cross-sensitivity testing, combining 2.5% Methane (50% LEL equivalent) with 500 PPM Ethane.
Balanced in air, this mixture enables realistic combustion sensor response, making it ideal for calibrating catalytic bead and combustible gas detectors under true operating conditions.
The 66-liter aluminum cylinder provides a portable, mid-capacity solution for routine calibration, field service, and compliance verification.
