Product Description
Ethane (C₂H₆) / Methane (CH₄) 50% LEL Calibration Gas – 221L Cylinder
This ethane 50 ppm / methane 2.5% (50% LEL) calibration gas mixture is designed for calibration of combustible gas detection systems requiring higher LEL threshold validation with controlled gas delivery. Supplied in a 221 liter steel cylinder at 250 PSI with CGA-165 valve, this non-reactive blend provides stable gas concentrations for consistent detector performance over extended calibration cycles.
