description

The Dräger Polytron 7000 is a stationary gas detector and is used for the
monitoring of toxic gases and oxygen. The device converts the measured gas
concentration into an electrical signal for further processing.

Frequency of the calculation of the measured value: 1 x per second (updating of the
display, the 4-20-mA interface and the relays).

NOTICE

Indicates a potentially hazardous situation
which, if not avoided, could result in dam-
age to the product or environment.
