Product Description
High Capacity Confined Space Calibration Gas – 120L Cylinder
This reduced-oxygen calibration mixture is used by facilities that perform frequent monitor verification and need extended service intervals between cylinder replacement.
The 19.0% oxygen concentration confirms deficiency alarm performance while hydrogen sulfide, carbon monoxide, and combustible sensors are validated simultaneously.
The 120L cylinder supports centralized bump-test stations and multi-instrument maintenance programs.
