Passive heater
The “Designer” section has a calculation tool to be used in case the sampling pipe needs to take air from environments with a temperature very different from the one in witch it is located the FA100 device, or with temperatures not acceptable for measurement.
This tool is usable through a window that opens and requires related data of the sampling and measurement environments (where the detector is located), the pipe (geometry and material) and the suction flow. The data can be entered manually or by selecting, through the boxes above, the device and the detector. In this way, the software will automatically fill the flow related fields, temperature, altitude and diameter.
The calculation start button 
gives us back a curve that shows how the temperature of the aspirated air in the pipe varies in function of the distance travelled.
Note
In the calculation, it is assumed that all holes are located within a single room at a constant temperature and that the distance considered corresponds to the section of the tube between the exit from the sampling environment and the entrance to the detector.
As the air passes through the tube, if the temperature of the environment is different, it gradually heats up or cools down.
The graphic evidence with a pink colour the aria with unaccettable temperatures (lower than -10° or higher than 55° C).
