Product Description
44L 4-Gas Calibration Gas – Compact Cylinder for Field Technicians
This 44 Liter reactive 4-gas calibration cylinder is designed for technicians who need reliable detector verification without carrying higher-volume cylinders into the field.
Blend configuration:
-
Hydrogen Sulfide (H₂S) – 10 PPM
-
Carbon Monoxide (CO) – 50 PPM
-
Methane (CH₄) – 2.5% (50% LEL)
-
Oxygen (O₂) – 20.9%
-
Nitrogen Balance
With 20.9% oxygen replicating atmospheric conditions, this mixture allows full multi-channel validation — toxic, combustible, and oxygen sensors — during routine bump testing or scheduled calibration intervals.
The 44L format offers practical handling, easier transport, and space efficiency for contractors, maintenance teams, and safety supervisors operating across multiple job sites.
