Product Description
4-Gas Calibration Gas – 25 PPM H2S / 200 PPM CO / 2.5% (50% LEL) CH4 / 20.0% O2 – 34L C-10 Disposable Cylinder
This 4-gas calibration blend is engineered for elevated carbon monoxide validation and controlled oxygen variance testing in a compact, disposable 34L cylinder format.
The 200 PPM Carbon Monoxide concentration supports moderate high-threshold CO alarm verification, while 20.0% oxygen allows confirmation of oxygen sensor performance under slight atmospheric deviation conditions without simulating deficiency environments.
Concentration profile:
-
25 PPM Hydrogen Sulfide for toxic channel calibration
-
200 PPM Carbon Monoxide for elevated CO alarm validation
-
2.5% Methane (50% LEL) for combustible sensor testing
-
20.0% Oxygen for oxygen baseline variance verification
Typical applications include:
-
Portable multi-gas monitor calibration
-
Service truck and field technician programs
-
Short-duration bump testing schedules
-
Replacement inventory for safety teams
-
Low-volume detector fleets
The 34L disposable cylinder is optimized for convenience, simplified logistics, and reduced storage footprint.
