1.3.3 Sample / Calibration Gas Flow Adaptor
(1226A0411)
A Flow Adaptor provides a facility to allow sampling of a closed system by means
of two pipelines. The Flow Adaptor is tted to the sensor accessory thread by a
locking ring that enables the Flow Adaptor to be removed without disconnecting
the pipeline. The Filter is retained by the Flow Adaptor and interfaces with a gasket
bonded to the Flow Adaptor. The Flow Adaptor ports are designed to be tted
with 1/4 in (6mm) soft tubing.
The Flow Adaptor is also used to apply calibration gas to the sensor. See Section
7 - Calibration for further details on calibrating the detector.

1.3.4 Gassing Point Assembly
(1226A0354)
The Gassing Point Assembly assembly can be xed in a convenient position and
permanently connected by suitable tubing to an inaccessible sensor, thus simplifying
the application of test gas when checking sensor calibration. A DIN Rail Mounting
Assembly (00785-A-0069) is available to enable ve gassing point assemblies to
be mounted side by side.
