The Dräger Polytron 7000 is a gas detector that can satisfy all toxic and oxygen gas measurement applications on a single platform. It is meeting the requirements of the compliance market as well as the high specification requirements of customized solutions. Developed with an innovative modular design, there is now the flexibility to choose and purchase only the features that the application requires. The unit is upgradeable to a higher specification after it has been installed simply by adding modules. This allows the Dräger Polytron 7000 to develop in line with changing application requirements.  





Intuitive operation - The software menu of the Dräger Polytron 7000 was designed in partnership with our customers making it simple and easy to use. The large graphical display uses icons and plain text to show the status of the instrument, and guides the user through calibration and configuration. Calibration has been made even easier with the auto-calibration function.





Intelligent sensors - With over 30 different DrägerSernsors to choose from, the Dräger Polytron 7000 is able to detect over 100 different gases. Specifically designed for the demanding requirements of a 24 hours a day, 365 days a year stationery gas detection system, the larger DrägerSensor are renown for their long life times and superior performance. The embedded sensor memory contains information on gas, range, cross-sensitivities, calibration values, temperature compensation, speedy sensor warm-up, and sensor-vitality data. All this enables the use of pre-calibrated sensors, which makes the Dräger Polytron 7000 ideal for a virtually maintenance free transmitter.


Communication interfaces - With the Dräger Polytron 7000 the communication to the central control system can be selected between 4 to 20 mA, HART fieldbus or LONWORKS. With the LONWORKS option, the Dräger Polytron 7000 can be integrated into any LONWORKS system architecture. Offering the advantage of reduced wiring cost and a reliable and flexible communication network. HART enables a simultaneous 4 to 20 mA signal and digital communication via the same single twisted pair line. Alternatively, up to eight transmitters can be daisy chained for operation on a single twisted pair connection in full digital mode.





Software Options - A number of software dongles with different software functionality will customize the transmitter to specific application needs.





Sensor Test Dongle  


With this dongle, the Dräger Polytron 7000 performs many patented sensor tests to ensure reliability and functionality of the sensor and the gas detection system.





Sensor Diagnostic Dongle  


All sensors have a certain life time which can be affected by factors such as gas exposure, temperature exposure and the age of the sensor. Now, with the new sensor diagnostic function in the dongle (including Sensor Test), the stress and remaining life of the sensor is evaluated, and it is possible to predict and plan for a maintenance and replacement cycle.





Data Dongle  


Datalogger and eventlogger options are implemented in this dongle, which stores gas values and events such as faults and alarms. Using an IR link with the PDA m515-Ex, the data can be downloaded and evaluated on a PC with the GasVision software. By pushing one button, a graphical 15 minute history of the gas concentration will be displayed on the transmitter screen, for quick evaluation of the current and past situation.





Simple, quick installation - The Dräger two component concept of a Docking Station and a Dräger Polytron 7000 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 7000 electronics is fixed by quick-lock mechanism into the Docking Station, the sensor inserted - and the system is ready for operation.





Rugged Housing - The design of the compact durable GRP housing of the Dräger Polytron 7000 is dust and water proof with an IP66/67 and NEMA 4 rating. It is verified to SIL 2 specification with unsurpassed RFI resistance.





Relay Module - The Dräger Polytron 7000 can be equipped with a relay module to make it a stand alone device with two gas alarms and one fault relay. The relay module forms a part of transmitter, so there is no additional installation cost or wiring to be done. For general purpose use only.*





Pump Module - An internal pump for sampling the gas mixture to the sensor is also a module option. The pump fits inside the Dräger Polytron 7000 with no additional need for extra wiring and mounting space. For general purpose use only.*





Accessories / Remote Sensor - The remote sensor is easy to install on the wall or, using the duct adapter, onto ducts and pipes (curvature diameter > 10 cm / 4”, up to flat). It is available with a cable length of 5 to 30 m / 15 to 100 ft.





Duct Mount Kit - The duct mount kit enables direct mounting of the Dräger Polytron 7000 onto ducts and pipes (curvature diameter > 10 cm / 4”, up to flat).
