Product Description
CO 60 PPM / CH₄ 50% LEL / O₂ 15.0% Calibration Gas – 103L Cylinder
This multi-gas calibration gas mixture is designed for extreme environment validation, where accurate detector response is critical under severe oxygen-deficient conditions.
The blend includes Carbon Monoxide (CO) 60 PPM for low-range toxic gas calibration, Methane (CH₄) 2.5% (50% LEL) for high-level combustible gas response testing, and Oxygen (O₂) 15.0% to simulate dangerous oxygen-deficient atmospheres. This combination ensures gas detectors are validated against both toxic exposure thresholds and elevated explosive risk in a single calibration process.
Housed in a 103L steel cylinder at 1000 PSI with a C-10 valve, this configuration delivers a balanced capacity—providing enough volume for repeated calibration without the handling limitations of larger cylinders.
