Easy operation
Dräger developed the simple and structured software menu of the Polytron 7000 in collaboration with its customers. The big graphic display shows status information with the help of icons and plain text, and guides the user through calibration and configuration.

Communication interfaces
The wide range of outputs, 4 to 20 mA, HART®, LON, PROFIBUS® or FOUNDATION Fieldbus™, enables the connect of the Polytron 7000 with a control system. The modular design allows for the subsequent retrofit onto any of the mentioned interfaces.

Remote Sensor
The remote sensor adapter can be easily mounted on a wall, or, in combination with the pipe adapter, on exhaust ducts or pipelines.

Relay module
The Dräger Polytron 7000 can be equipped with a relay module. This turns it into an independent gas warning system with two concentration alarms and one fault alarm.

Intelligent sensors
The Dräger Polytron 7000 can detect over 100 different gases. DrägerSensors are specifically designed for the demands of 24 hours per day, 365 days per year operation. The large DrägerSensor size gives them their renowned long life. The built-in sensor data memory containing all the relevant gas and calibration information, together with on board temperature and pressure compensation gives the DrägerSensor its unsurpassed measurement performance. This also allows the Polytron 7000 to accept pre-calibrated sensors, with minimal operator intervention, the Dräger Polytron 7000 is a virtually maintenance free transmitter.

Software options
With three different software dongles, a range of functions are incorporated into the transmitter adjusting it to user or application specific requirements.With the sensor test dongle, the Dräger Polytron 7000 performs many different patented sensor tests that ensure the reliability and functionality of the sensor and gas detection system. With the sensor diagnosis function (including the sensor test), operational demands and the remaining sensor life time is estimated so that maintenance and exchange schedules can be created. A data and event saving option is integrated into the data dongle. This saves the measured values and events such as alarms and warnings. The data can be downloaded via an IR interface and evaluated on a PC with the Polysoft software. At the push of a button, a 15-minute concentration curve is shown on the transmitter display.

Pump module
The inclusion of a pump module enables the Polytron 7000 to draw gas samples from difficult to reach areas, the gas sample is then passed across the DrägerSensor for detection. The pump unit, like all accessories in the Polytron 7000 range is modular, and can be retrofitted into existing transmitters. (Not suitable for use in hazardous areas)
