Product Description
Low Oxygen Four Gas Calibration Gas – 66L Cylinder
This calibration mixture is engineered for environments where oxygen deficiency detection must be verified alongside toxic and combustible hazards.
The reduced 19.0% oxygen level allows technicians to confirm monitor response before entry into controlled or ventilation-limited spaces.
The 66L cylinder size is commonly used for portable detector maintenance programs and daily bump testing routines.
