The Drager Polytron 2 XP Tox is an explosion-proof Gas Detector for continuous monitoring of toxic gases and oxygen in ambient air. It converts the signal from an electrochemical sensor to a 4 to 20 mA analog or HART or RS 485 digital signal output.
The Polytron 2 XP Tox is designed for one-man calibration and offers a variety of diagnostics and self-test features.

Benefits:
Easy to install
The enclosure provides 2 mounting holes. For easy wiring, the electronics is enclosed in a bucket and can be pulled out as one unit, held by a tether. The 3 wire cable, fed through a sealed conduit, is terminated in a pluggable connector at the printed circuit board.
Stand-alone system
With the 3 built-in relays, the Draeger Polytron 2 XP Tox can be used as an independent stand-alone unit. Two adjustable gas alarm levels and a fault alarm make it convenient to switch warning devices on-site, without having to run cables back and forth to a central controller. The sensor signal can still be transmitted using either the 4 to 20 mA, HART or RS 485 signal output.
