The Draeger Polytron® 8720 IR is an advanced explosion proof transmitter for the detection of carbon dioxide in percent volume or ppm. It uses a high performance infrared Draeger PIR 7200 sensor, which can be submerged in water without damage.
With its stainless steel 316L enclosure and drift free optics, the Draeger PIR 7200 is built for the harshest industrial and commercial outdoor environments. The unique 4 beam signal stabilizing system makes the sensor resistant to dust or dirt deposits on the optical surfaces. Environmental and aging effects are compensated ensuring long term, drift free operation. The measuring range can be freely adjusted between 0 – 2,000 ppm and 0 – 30% volume enabling a wide variety of applications.
The Draeger Polytron 8720 is equipped with digital interfaces allowing for quick and easy remote interrogation of the transmitter’s state. Integration with existing asset management systems such as PACTware™ is possible via DTM.
The Draeger Polytron 8720 belongs to the Polytron 8000 series. All transmitters in this series have the same design and user interface. This allows for uniform operation with reduced training and maintenance requirements.
