GX-6000 Operator’s Manual
The filter comes with a tubing stub and plug on each end. Both plugs must be removed
before using the filter and must be reinstalled for storage. The filter does not have a
preferred flow direction.
When used with a CO
2
scrubber, the VOC zero filter gets connected to the instrument and
the CO
2
scrubber gets connected to the VOC zero filter. See “Performing a Demand Zero
for Instruments with a Carbon Dioxide Sensor and a PID Sensor” on page 203 for more
instructions.

External Dilution Fitting
A 1:1 external dilution fitting is available for the GX-6000. It is designed to mate with the
inlet fitting and accept the sample hose and probe. The fitting is made with brass and
nickel plated brass and is appropriate for use with the four standard gases. The fitting is
normally used when it is necessary to introduce air into a sample that has no oxygen or a
very low level of oxygen, such as a nitrogen purged sample. It can also be used when one
of the target gas levels in the sample area will likely be present in a concentration above
the detection range for that gas. Since the fitting partially consists of unplated brass, it is
not appropriate for detection of elevated levels of H
2
S or of gases that are easily absorbed
such as Cl
2
or SO
2
.

DIN Rail Mounting Assembly
Two different DIN rail mounting assemblies are available for the GX-6000’s charger. Each
assembly has two end clamps but one assembly is long enough to accommodate 1 charger
and the other assembly is long enough to accommodate 4 chargers.
