Designed for chemically stable gases, this steel or aluminium cylinder holds mixtures such as methane, carbon dioxide, oxygen, pentane and propane. Because these components do not react with the cylinder wall, no special surface treatment is required, delivering long shelf life and consistent concentrations for reliable calibration of combustible and oxygen sensors.
The Non-Reactive Gas Mixture Cylinder provides a cost-effective, dependable reference source for the many calibration tasks that involve stable gas components. Mixtures containing methane, carbon dioxide, oxygen, pentane or propane remain chemically inert against standard cylinder walls, so they retain their certified concentrations over a long shelf life without the need for specialised internal passivation. This allows the cylinder to be manufactured in either steel or aluminium, giving flexibility on cost, capacity and pressure to suit different site requirements across the GCC and India.
Widely used for calibrating combustible gas sensors at the lower explosive limit, oxygen monitors and carbon dioxide instruments, the cylinder charges detectors with a precise, traceable reference value during span calibration and bump testing. Each unit is supplied with certification documenting the concentration at fill, supporting audit trails and safety compliance. A robust valve accepts demand-flow or fixed-flow regulators for controlled delivery to portable and fixed instruments alike. With its combination of long stability, straightforward handling and economical construction, this cylinder is a versatile mainstay for routine calibration programmes wherever stable gases are involved.
