Polytron 5720

Dräger Polytron® 5720 IR explosion-proof Transmitter


The Dräger Polytron® 5720 IR is an explosion-proof Transmitter for the detection of carbon dioxide in volume percentage or ppm. It uses a high-performance infrared Dräger PIR 7200 sensor that can be submerged in water without damage. A 3-wire 4-to-20 mA analogue output with relays makes it compatible with most control systems.
