Dräger Polytron® 7500

All in one enclosure: The Dräger Polytron 7500 is a pyrolyzer for the continual monitoring of toxic gases and halogenated carbons in the ambient air. The device contains all necessary functions such as sampling, processing and analysis.

Reliable measurements

​The suitable temperature inside the pyrolysis oven in conjunction with a suitable sensor allows for the selective measurement of nitrogen trifluoride NF3 or fluorized/chlorized organic compounds such as C4F6, C5F8 and other PFCs. The advanced electronic design and a shielded full metal enclosure guarantee an operation without interferences.

Software options

​With three optional software dongles, different functionalities such as sensor texts, sensor diagnoses and data logging can be retrofitted.

Gas sampling

​The pyrolyzer is equipped with two internal pumps and two independent electronic Flow monitors. A pump provides the Polytron 7500 with a gas sample. The second pump provides the oven and the sensor with constant gas flow. A tube flow sensor guarantees fast visual feedback for proper operation.

Easy to use

​Icons and text on the big graphic display show the status of the device and guide the user through calibration and configuration. The new software menu with password protection developed in collaboration with customers is easy to use and, therefore, highly convincing: Three buttons suffice to call up the different functions.

Different communication interfaces

​In addition to the analog 4 to 20 mA signal, a HART®-Fieldbus is available. With the LONWORKS® option, the Dräger Polytron 7500 can be integrated into any LONWORKS® system architecture.

​Relay module

The Dräger Polytron 7500 can be equipped with a relay module in order to use it as a stand-alone unit with two gas alarm and fault relay.
