The systems are not designed for use in an explosive atmosphere.
Irreversible system damage might occur if the use of adequate and application-specific gas
filtration technology is omitted. This is an optical measurement system.
For further
information on gas conditioning and filtering please refer to Chapter 2.6.
Relative humidity in the measurement gas and measurement conditions must be such that
no condensation occurs inside the measurement cell.
Each sensing module is calibrated to a certain gas temperature and pressure. Deviations in
both parameters can lead to significant degrading of measurement accuracy.
The LGD F200P2 instrument continuously measures the gas concentration in the measurement cell.
Default measurement time is roughly 1 s (user changeable to up to 600 s integration time or “averaging”).
The ambient version has a start-up time of 30 s to give a correct concentration reading. The warm-up time
for the heated version depends on the set-temperature and ambient conditions. For a measurement set-
temperature of 190°C / 374
F, about 30 min are needed (40 min for 220°C / 428
F option). Depending on
ambient conditions, it may take longer until all components have reached a stable temperature.

For any shipments of the system, it is recommended to retain and re-use the original shipment material,
which has been tested and proven to be effective protection. Relevant Operation & Storage conditions as
described above as well as in the Product Datasheet need to be respected for shipment. In case of a
return, Axetris AG will not be responsible for shipping damage as a result of improperly packaged systems
and recommends customers ship systems insured for full value.
2.2 System layout and materials
Do not open the system. Opening might lead to irreversible damage.
Do not remove the fittings of the measurement cell.
Prevent any dust, insulation or other material from entering the measurement cell.
The main external features of the LGD F200P2 are the housing, the electronics housing, and the gas-in
and gas-out connectors. On the inside, the system is equipped with an electro-optic module containing a
laser and photo-diode, a measurement cell, and a high reflectivity mirror. The laser beam traverses the
measurement cell from the electro-optic module to the mirror and then goes back through the
measurement cell to the photo-diode. Small air spaces are necessary for thermally decoupling the electro-
optic module and the mirror from the measurement cell that can optionally be heated as high as 220°C /
