Other Accessories
Several other accessories are available for the GX-6000. This section
describes the VOC zero filter, the dilution fitting, and the DIN rail. Detailed
instructions regarding the use of the dilution fitting are included in other parts
of this manual. Data logging accessories are briefly described in “Data
Logging” on page 66.
VOC Zero Filter
A VOC zero filter is included as standard with GX-6000s that include:
• Low range PID sensor (PID-001L)
• 10.0 eV/benzene PID sensor (PID-003L)
• Any PID sensor and
any CO
2
sensor
The VOC zero filter scrubs out low levels of VOC gases using charcoal. Use
the VOC zero filter when:
• Performing an air adjust on a PID sensor in an area that may have a low-
level VOC background.
• Performing an air adjust on a PID/CO
2
instrument (in combination with a
CO
2
scrubber).
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 198 for more instructions.
