WARNING!
Physical injuries and damage to property and the
environment caused by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene,
flammable or toxic substances), harmful media (e.g. corrosive,
toxic, carcinogenic, radioactive), and also with refrigeration
plants and compressors, there is a danger of physical injuries
and damage to property and the environment.
Should a failure occur, aggressive media with extremely high
temperature and under high pressure or vacuum may be
present at the instrument.
For these media, in addition to all standard regulations,
the appropriate existing codes or regulations must also be
followed.
For contact details see chapter 1 "General information" or the
back page of the operating instructions.
