OMG200N1.23 G200 Analyzer Range
VIASENSOR Page 6
2.0 Introduction
This manual explains how to use the instrument model types listed below:
•G200 N20 0-1,000ppm (plus 10,000 range low resolution)
•G210 N20 0-100%+CO2 0-2,000ppm+O2 0-100%+CO 0-500ppm
The G200 analyzer is specifically designed to safety check background levels of N2O (0-
1,000ppm) in medical applications. The G210 analyzer is specifically designed for highly
accurate measurement and verification of the quality of piped medical gases in hospitals. Both
units have been developed to incorporate the latest technology and specification
requirements, which provide the user with a fast, simple-to-use and accurate piece of
monitoring instrumentation.
Note: These instruments are sensitive pieces of scientific equipment, and should be
treated as such.
2.1 The G200 Analyzer
The G200 analyzer is specifically designed to safety check background zone levels of N2O
(0-1,000ppm) in medical applications. This instrument measures the long term exposure to
N2O gas along with the TWA (time weighted average), leak detection for N2O storage. It is
a dual purpose background analyzer or personal analyzer and is highly portable.
The G200 analyzer has the following features:
•O2, N20 0-1,000ppm
•Data storage for 1,000 readings and download
•EH40 occupational exposure limits calculated (TWA) –applicable to the UK only
•Leak detection
•User settable alarms
•Data download for graphing and reporting

•Four modes of operation: personal safety - TWA 8 hour read back; room monitor –
background levels, user defined times; leak mode –1-10,000ppm fast response; and
standard measuring.
2.2 The G210 Analyzer
The G210 analyzer is specifically designed for highly accurate measurement and verification
of the quality of piped N2O and O2gases in hospitals. This instrument enables up to four
gases to be measured, easy user calibration, quick verification of gas quality, user
maintained site and sample point IDs for monitoring as well as identification of
contaminants CO and CO2.
The analyzer has the following features:
•N2O 0-100%
•O2 0-100% (optional)
•CO 0-500ppm (optional)
•CO20-2,000ppm
•Data storage with site and ID input
•Data download for graphing and reporting

3.0 G200 Range Optional Products and Accessories
3.1 Optional Products
The G200 analyzer range has a number of optional products for purchase which enhance the
usability and enable further analysis of data and reading information.
Note: For further information, please contact Sales at VIASENSOR Toll Free
(855) VIASENSOR, [phone] or email [e-mail].
3.1.1 Analyzer Data Manager (Optional)
Analyzer Data Manager software application enables the operator to maximize the
operation of the analyzer by providing the ability to:
•Obtain instrument status.
•View the instrument readings and event log data.
•Download and store readings for further analysis.
•Graph downloaded instrument readings.
•View, import and export the instrument configuration.
•Update the instrument’s firmware.
•Copy data from the G200 Client into other packages such as MS Excel.
•Email data directly from the application.
•Configure remote access to a central database.
•Print graph and tabular data.
3.1.1.1 Event Log
The G200 range of instruments incorporates the facility to log significant events via the
‘Event Log’. This can be used as an aid to monitoring the use of the instrument. It can
also be used as a diagnostic tool if there is a problem with the instrument.
The event log can only be viewed via the optional Analyzer Data Manager software. It
cannot be viewed on the analyzer screen. Applicable events are stored in the event log
automatically. No user intervention is required.
The event log can hold approximately 270 events. If the log becomes full then it begins
to overwrite the older events. This can be identified by the index field which starts from
event number 1. The log is cleared when the instrument is reset.
Note: Please refer to section ‘12.0 Event Log’ of this operating manual for further
information.
3.1.2 Carbon Monoxide Reading (Optional - G210 ONLY)
The G210 instrument has the optional facility to use an internal CO cell (specified at the
time of manufacture). This allows the instrument to read and display carbon monoxide
readings along with N2O.
3.1.3 Oxygen Reading (Optional –G210 ONLY)
The G210 instrument has the optional facility to use an internal oxygen cell (specified at
the time of manufacture). This allows the instrument to read and display oxygen readings
along with N2O, CO2, CO.
3.1.4 Pressure Regulator Kit (G210 ONLY)
A pressure regulator kit must be used when taking gas readings to restrict the flow into
the instrument when using the G210 analyzer. When sampling piped medical gases the
pressure of the gas needs to be reduced before it is passed to the instrument. This

OMG200N1.23 G200 Analyzer Range
VIASENSOR Page 10
reduces the pressure to 40.15” W.C. suitable for the instrument. It is recommended that
the operator uses the pressure regulator kit supplied by VIASENSOR.
Warning
Do NOT use the instrument at full piped pressure (maximum
pressure 120.44” W.C.).
3.1.5 Soda Lime CO2Filter
This filter is designed to remove ambient CO2 (up to 1500ppm) from the sample gas. For
the G100 range of instruments, it should only be fitted when user zeroing the CO2
Channel in air, thus emulating an equivalent zero in N2. Using the filter is highly
recommended when N2 gas is unavailable and performs a much better zero than selecting
zero with air which assumes 400ppm is present. The actual concentration of CO2 in the air
can vary greatly depending on the environment and can lead to incorrect user calibration.
This filter should always be fitted when using a G200 instrument as any CO2 will cross-
contaminate the N2O reading.
The life of the filter will vary depending on usage. The crystals change color from white to
violet. The filter element should be discarded when a significant percentage of the crystals
start to turn a violet color –see below:
Assemble Filter and Connect to Instrument as Shown
New Filter (White)
Used Filter (Violet)
The filters are supplied in a sealed storage bag to
improve their shelf life. The parts supplied should be
assembled as per the diagram shown. Please note the
sample filter is still in place.
