SAFETY INFORMATION 1
1.1.3 Protection against hazards through gases
WARNING: Hot and/or aggressive sample gases
▸Wear suitable protective clothing and mask when using hot and/or aggressive
sample gases and/or with high dust loads.
▸Never open the enclosure or switch off the purge air feed without taking appropriate
protective measures when the duct is pressurized.
WARNING: Toxic and caustic substances in parts in contact with sample gas
●Depending on the sample gas composition, parts of the GM700 in contact with
sample gas can contain toxic or caustic substances.
●When fitted in the measuring device, the reference cuvette contains the respective
gases to be measured. These gases must not escape.
Special care must be taken with the GME700-2 (HF) because this cell not only
contains gaseous HF but also a certain amount of liquid (max. 0.1 g HF for 8 cm
cell). HF / hydrofluoric acid is extremely toxic and caustic. It is imperative to avoid
inhaling or skin contact at all times. Particularly when there are indications of leaks
or defects, wear protective clothing (protective goggles, latex gloves) and carry out
work in a well ventilated room/area. Never open the cuvette under any circum-
stances. Check replacement cuvettes for any possible transport damage.
●Handle with care when test gases are used:
▸When handling HF, keep an HF emergency set (including calcium gluconate gel)
available.
▸Before working on the gas path, ask the operator which gases have been applied to
the GM700.
▸Ask the operator whether, and how, the gas path of the GM700 has been cleaned.
▸If necessary, clean the gas path with a suitable method.
▸In case of doubt, take appropriate protective measures before working on the gas
path: Ensure adequate ventilation at the workplace or work under a vent. Wear
protective goggles or a safety mask, protective gloves and acid-proof protective
clothes.
WARNING: Risk of fire through hot gas escaping in installations with
overpressure conditions
On installations with overpressure, the purge air hose can be severely
damaged by escaping hot gas and can catch fire depending on the
temperature.
On plants with overpressure as well as gas temperatures over 200°C:
▸Ensure reverse flow is prevented by fitting a (trip) flap or a valve.
▸Regularly check the functionality of the reverse flow safeguard.

2PRODUCT OVERVIEW
Sender/receiver unit (SR-unit)
The sender/receiver unit contains the optic and electronic subassemblies of the
measuring system. The gas concentration is captured here and the measured value
determined.
Measuring probe
Measuring probes are available in open design versions with integrated purge air guidance
system (GMP) as well as versions with agas permeable sinter filter not requiring purge air
(GPP: Gas Permeable Probe). Both versions are described from “Measuring probe in
detail”, page 19 onwards.
Purge air unit
To supply purge air to the SR-unit with open measuring probe (GMP) and thus to protect
against contamination and high gas temperatures. Use a certain purge air unit each for the
SR-unit depending on the application. The blower types for the SR-unit are designed
differently depending on the application.
Evaluation unit
The evaluation unit in the GM700 measuring system serves as user interface and is
responsible for measured value processing and output as well as control and monitoring
functions. The EvU can be located in the vicinity of the SR-unit. It can also be located up to
about 1000 meters from the sampling point, e.g. installed in the switch center or
monitoring center, and performs functions such as:
●Output of measured values, computed data and operating states
●Communication with the peripheral equipment
●Output of error messages and other status signals
●Control of automatic test functions and access during service (diagnosis)

PRODUCT OVERVIEW 2
Flange with tube
To install the purge air fixtures of the SR-unit and reflector on
the gas duct. The purge air fixture is fitted on the flange and
then the SR-unit is fitted on the purge air fixture. ANSI or DIN
flanges provided by the customer can be used alternatively to
the flanges supplied.
2.2.1 Measuring probe in detail
Fig. 5: GPP measuring probe with ceramic filter
Integrated sensors
All probe versions have a built-in pressure sensor as well as an integrated temperature
sensor PT 1000 that continually measures the medium temperature of the probe in the
active measuring path. The measured data are transferred via the CAN bus interface of the
measuring probe and can then be displayed on the evaluation unit.
EPA conformity
When using a GPP probe, an audit measurement conforming to EPA CFR 40 Part 60 and/
or Part 75 can be carried out with the device fitted as far as usable for the application.

2PRODUCT OVERVIEW
2.2.1.1 GMP probe with open measuring gap
Shortest reaction times and high temperature stability characterize the GMP series
measuring probes. Continuous purge air feed is required for operation. In the current GMP
probe series, the air is outlet into the duct at 90° to the gas flow (directed purge air). The
GMP probe has a locking device on the opening for sample gas that is activated with a
lever on the probe flange.

PRODUCT OVERVIEW 2
2.2.1.2 GPP gas diffusion probe in dry or wet version
This version is more suitable for higher dust contents because, on GPP probes, dust
particles are separated on the filter element and therefore kept away from the measuring
path. The GPP (Gas Permeable Probe) should also be chosen to allow an EPA-conform
audit measurement as well as for low flow speeds or irregular flow profiles.
Fig. 7: Measuring gap of the GPP measuring probe
Both variants of the GPP differ in the respective filter which provides suitability for different
application areas in accordance with Table “GM700 measuring probes in comparison”,
page 22.
Advantages of GPP probes
GPP probes do not require a purge air supply and are easy to maintain. They are fitted with
an automatically controlled heater to reliably prevent condensate on the optical interfaces.
The electronics for heating control, temperature and pressure measurement are located
reliably protected in a sturdy cast-metal enclosure acting as measuring probe section
between duct flange and SR-unit. Both the electric connections for CAN bus and power
supply as well as the test gas connection with which the audit measurement according to
EPA Guideline CFR 40, Part 60 or Part 75 can be carried out are located on the enclosure
as shown.
