Polytron 8700 IR Flammable Gas & Vapor Detector

Brand: Drägerwerk AG & Co. KG

The Dräger Polytron 8700 IR is an advanced explosion proof transmitter for the detection of combustible gases in the lower explosion limit (LEL). 

It uses a high performance infrared Dräger PIR 7000 sensor, which will quickly detect most common hydrocarbon gases. 

Besides a 3-Wire 4 to 20 mA Analog output with relays, it also offers Modbus and Fieldbus making it compatible with most control systems.
