Product Description
103L CO (10 PPM), CH₄ (50% LEL), and O₂ Calibration Gas – Durable Low-Level CO Calibration
This 103L custom calibration gas cylinder is designed for routine calibration programs requiring accurate low-level carbon monoxide detection with added durability for facility environments.
The mixture includes 10 PPM Carbon Monoxide (CO) for sensitive toxic gas calibration, 2.5% Methane (50% LEL) for standard combustible gas testing, and 20.9% Oxygen (O₂) to simulate normal atmospheric conditions.
This blend is ideal for multi-gas detector calibration where precise low-range CO accuracy and consistent LEL verification are required.
