4.0 GA5000 optional products and accessories
4.1 Optional products
The GA5000 gas analyzer has a number of optional products for purchase which enhance
the usability and enable further analysis of data and reading information.
Note: For more information on the features listed in this section please contact Sales
(800) 624-2026 or email
.
4.1.1 Temperature probe (optional)
The GA5000 gas analyzer has the facility to automatically display and record the
borehole temperature via an optional temperature probe.
When a temperature probe is fitted the temperature reading will be displayed on the
‘Main Gas Read Screen’ and recorded with all other data.
Note: Temperature probes with an Ex label are part of the GA5000 Ex certification
SIRA 11ATEX2197X and IECEx SIR11.0089X, and therefore certified for use
under the same conditions as the analyzer.
4.1.2 Anemometer (optional)
The GA5000 gas analyzer has the facility to automatically display and record high flow
via an optional anemometer probe. It is designed to plug into the instrument and
instantly provide a flow indication. An anemometer probe adds flow measurements to
the professional reporting ability of the GA5000 range along with gas concentrations,
pressure and temperature.
The anemometer has a simple connection, a narrow diameter measurement head
(11mm), a wide temperature operating range (up to 80
o
C) and indicates flows up to 40
m/sec.
When an anemometer probe is fitted to the analyzer the flow will be displayed in the
‘Main Gas Read Screen’ and recorded with all other data.
Flow can be measured in either m/s (gas velocity) or m
3
/hr (volume flow rate). In order
to calculate the volume flow rate the pipe diameter will need to be entered into the
instrument, either manually or via the Gas Analyzer Manager software.
Note: "The anemometer probe is ATEX certified for use in a potentially explosive
atmosphere under Ex certificate BVS 04ATEXE194.
4.1.3 H
2
S filter (optional)
The GA5000 gas analyzer has the capability to use an H
2
S filter and is required as
standard if the compensated CO cell is fitted and configured at the time the instrument is
manufactured. H
2
S gas can have a cross-gas effect on the CO reading. By using a filter,
the H
2
S is removed from the gas sample, therefore providing a more accurate CO
reading.
The filter only needs to be used when you are trying to get rid of any possible cross gas
effects H
2
S might have on other gases. Do not use the filter on all boreholes.
