It is sometimes beneficial to attach more than one analyzer, and/or accessory device, or different
inlet ports to a single gas supply. Any time this is done, it is critically important that there be a
means of isolating, or shutting-off, each device attached to the gas supply regulator. Micromeritics
recommends the use of a vacuum rated shutoff/isolation valve for this purpose.
This shutoff/isolation valve is required in order to prevent problems when changing gas cylinders
or servicing any of the devices attached to the gas supply.
If the need to attach more than one inlet or one analyzer and/or accessory device is anticipated,
one or more of the following regulator expansion kits must be acquired:
