Page 7: Important Notes
1.2.2 Point of use The iFiD Mobile NMHC is designed for operation in well-ventilated rooms as well as for field measurements. The measuring device must be protected from direct atmospheric influences such as weather (wind, precipitation, sun), as influences of this kind can damage the device and reduce measuring accuracy. -
