The Drager Polytron 7000 is an intrinsically safe fixed gas detector for toxic and oxygen gases. Operated by three buttons, two arrows for menu navigating and an OK button for selection, developed in conjunction with users. Status can be viewed at a glance using icons or plain text. Menus guide the operator when undertaking configuration or calibration.

Two components make up the Polytron 7000. The transmitter itself and the docking station are ordered separately. This design allows easy installation; a docking station can be wired in initially,  the Polytron transmitter then clips into the docking station, secured by a quick-lock mechanism.

With over 100 Drager sensors available, calibration and configuration data are pre-loaded, making commissioning and maintenance fast.

Based around a modular design so customers can add functionality tailored to their applications.
