Instead of that sampling from process gas and external measurement are necessary. With the Integral Measuring Concepts of the Series IMC ExTox offers efficient solutions even for these measuring tasks. This Series combines all necessary components from sampling of meas- ured gas, preparation, sensor techniques and evaluation in one compact wall mounting housing. - Page 6 The flame arrestor is connected pre- vious to the measured gas inlet. When returning the measured gas into the process (Hint: Not recommended by ExTox) another flame arrestor at the measured gas outlet is necessary. (Compact-) Measured gas cooler incl.

Page 20: Application Hints
In general we do not recommend an installation outside, as in principle measuring accuracy and lifetime are influenced in a negative way. In case it is however necessary, please contact ExTox to design a suitable type. For this the following measures are necessary: control unit to be in- stalled inside, enclosure heating and rain protection cover for housing fans. -
