Product Description
44L 12.0% O₂ Calibration Gas – Portable Ultra-Deficiency Verification
This 44L reactive 4-gas calibration cylinder simulates ultra-low oxygen environments at 12.0% O₂, allowing confirmation of alarm activation under severe depletion conditions.
At 12.0% oxygen, atmospheric safety margins are significantly exceeded, making this blend suitable for advanced confined space and contractor-level verification programs.
Gas Mixture
