This product is now obsolete and has been replaced by the Polytron 8000.

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

The configuration and calibration of the transmitter is menu guided and easy to perform, using either the infrared remote control, the built-in push buttons, or a HART hand held terminal. With the optional relays, Polytron 2 XP Tox can be operated as 'stand alone' unit.

Easy to install - The enclosure provides two 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 three wire cable, fed through a sealed conduit, is terminated in a pluggable connector at the printed circuit board.

DragerSensor technology - High sensitivity, long term stability and no false alarms are the hallmark of the new and improved third generation of sensors. Sensors are the keystones of any gas detection system. Fastest response to the target gas combined with minimal interference by other gases or environmental influences (no false alarms) as well as the sensor life-time determine the reliability and the operating cost of a system.

One man calibration - All setup and maintenance can be performed without opening the transmitter or declassifying the hazardous area. An infrared remote control, beaming through the window, gives full access to the menu and calibration procedure. The menu can also be accessed using the built-in push buttons or a HART hand held terminal. All menu items and messages are displayed in plain English. Other, user selectable languages are French, Spanish and German.

Stand alone system - With the three built-in relays, 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.
