Product Description
680L CO (10 PPM), CH₄ (50% LEL), and O₂ Calibration Gas – Bulk Low-Level CO Calibration
This 680L custom calibration gas cylinder is designed for large-scale calibration programs requiring low-level carbon monoxide accuracy and consistent combustible gas verification.
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 combination is ideal for facilities managing high volumes of multi-gas detectors that require precise low-range CO calibration with consistent LEL verification.
