The Draeger Polytron® 5720 IR is a cost effective 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 Polytron® 5720 IR 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 – 2000 ppm and 0 – 30% volume enabling a wide variety of applications.
Polytron 5720 belongs to the Draeger Polytron 5000 series. All transmitters in this series have the same design and user interface. This allows for uniform operation with reduced training and maintenance requirements.
