Drager Polytron 7000

Designed in co-operation with our customers the Dräger Polytron 7000 is the leader of the next generation of intrinsically safe toxic and oxygen gas detectors. The goal behind the development was to service our customers and their wide variety of requirements and applications on a single, modular platform. The Dräger Polytron 7000 is able to adapt in line with the changing specifications of the application.

It is the first part of a new generation of gas detectors developed on a modular platform. Communication to the central control system is done via a 4 to 20 mA signal. The Dräger Polytron 3000 is available with or without display, in over 60 versions for different gases and set ranges. Simple, quick installation The two component concept of a Docking Station and a Dräger Polytron 3000 electronics saves time and money. The Docking Station can be pre-installed – mounting and wiring it into place separately – while protected by a rain and dust cover until commissioning. At commissioning, the Dräger Polytron 3000 electronics is fixed by a quicklock mechanism into the Docking Station, the sensor inserted - and the system is ready for operation. Easy to operate The Dräger Polytron 3000 is easy to handle with simple maintenance procedures. The DrägerSensors are equipped with a data memory where the calibration information is stored. This allows the Dräger Polytron 3000 to either accept a precalibrated sensor, or the sensor can be calibrated with the transmitter. Digital temperature compensation of the sensor signal is automatically performed.
