1.2 Intended Use
• Messkonzept GmbH does not assume any liability in case of improper handling of the measuring
device. Improper handling can cause hazards due to malfunction of the measuring device.
• The FTC-series of gas analyzers offer high-precision measurement and detection of non-corrosive,
dust-, condensate-, aerosol and oil mist-free gases (unless the design of the equipment is explic-
itly declared to be suitable for this purpose). Please contact info@messkonzept.de for detailed
information and solutions.
• The specifications listed in the appendix of these operating instructions reflect the conditions
under which the products described here may be operated. Individual requirements resulting
from the customer’s measuring task are determined and recorded with the Measuring Task
Questionnaire (German: Messaufgabe 2.01.1FB180619MPL1V007, English: Measuring Task
2.01.1FB180619MPL1V007). Requirements that are not specified by the customer in the ques-
tionnaire are not taken into account in the mandatory evaluation of the measuring task by Messkonzept
GmbH. In the evaluation of the measurement task by Messkonzept GmbH, it is also recorded
whether the measurement task can be carried out with the proposed devices. In addition, re-
strictions can be demanded by Messkonzept GmbH, which must then be implemented by the
customer. These restrictions can include, for example, special conditioning of the measuring
sample by filter measures and measuring gas coolers or specifications of the pressure and flow
rate ranges.
• FTC-series gas analyzers do not have a metrology marking in the sense of EU directive 2014/32/EU.
They can, therefore, also not be used in medical or pharmaceutical laboratory analyses or in the
manufacture of pharmaceuticals in pharmacies based on a doctor’s prescription.
• The device must not be used in hazardous areas of explosion protection. Only FTC320 measuring
instruments marked EX II 3G Ex nR IIC T4 Gc are suitable for use in ATEX- Zone 2.
• Flammable gases: Depending on the design, the measuring device is also suitable for the intro-
duction of flammable gases. Whether this is the case can be found in the device log under the
item "Glass bead filling". Measuring instruments with glass bead filling are also suitable for the
introduction of combustible gases. The interior of the housing is tightly filled with glass balls (Ø
0.6mm). Due to the dense filling with the inert material, the volume that can be filled by a gas
in the measuring device is reduced and segmented to such an extent that no explosive zone is
created in the measuring device even if there is a leak in the measuring gas path.
• Explosive gases: Our gas detectors are designed in such a way that gases introduced up to
temperature class T3 will not ignite if operated properly; the maximum surface temperature is be-
low 200 °C. Users of our gas detectors must always carry out an individual risk assessment before
such use, from which the necessary protective measures are to be derived and implemented. The
use of flame arresters as part of the individual concept for handling ignitable mixtures is strongly
recommended. If desired, we will be pleased to submit an individual offer to you if you require
flame arresters. Please use only devices with the glass bead filling option described above even
with this hazard.
• Check the function and tightness of our gas detectors, the connections and piping and the protec-
tive devices after installation and then at regular intervals during operation, especially in the event
of severe stresses, such as shocks, vibrations, and corrosive attacks from inside or outside. If you
