Drager Polytron IR CO2 Gas Detector

The Drager Polytron IR CO2 is a Gas Detector for continuous monitoring of carbon dioxide. It offers all benefits of fail-safe IR measurement technology for applications in rough environments. The transmitter uses microprocessor technology to convert the signal to a 4 to 20 mA analog output.

The Draeger Polytron IR CO2 Gas Detector 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 the built-in push buttons. With the ATEX-approval (device category II 2G acc. to 94/9/EC) the Drager Polytron IR CO2 is suitable for use in potentially explosive atmospheres zone 1 and zone 2.

Features
Minimum maintenance required
Fast and accurate response
Linear output signal nearly independent of temperature and humidity
Adjustable measurement ranges from 2000 ppm up to 30% by vol.
Ex-approved version: intrinsic safe concept no heavy flameproof enclosure.

Benefits:
Comprehensive explosion protection
The explosion-approved versions of Drager Polytron IR CO2 are certified acc. to the directive 94/9/EC (ATEX 95) and marked by II 2G, indicating that they are suitable to be operated in zones 1 and 2.

Preventive maintenance
Without loss of measuring quality the Draeger Polytron IR CO2 transmits a warning signal if the optical system is prone to get dirty and thus potentially will lose sensitivity.
