Designed for use by the utilities, water and waste and local government departments, the new Draeger Polytron 3000 from Draeger (Germany) is an intrinsically safe gas detector for the continuous monitoring of toxic gases and oxygen in ambient air. Featuring innovative "docking station" and transmitter technology, it offers a very low cost of ownership, is simple to maintain and eliminates the need for traditional service. Equally at home in a boiler house or a municipal water treatment plant, the Polytron 3000 can be used to monitor the presence of a specific gas such as ammonia (NH3), carbon monoxide (CO), chlorine (CI2), hydrogen sulphide (H2S), nitrogen dioxide (NO2), nitrogen monoxide (NO), oxygen (O2), or sulphur dioxide (SO2).
Comprising two components known as a "docking station" and a transmitter, it enables the fast removal and replacement of "like-for-
like" sensors that are equipped with a data memory storing calibration information. The docking station can be pre-installed on walls
and pipes without special mounting plates and, at commissioning, can be easily connected to the transmitter by a quick-lock mechanism.
Designed to accept a pre-calibrated sensor, it also features digital temperature compensation and an LCD display.
Weighing just 800g, the Polytron 3000 measures 175 x 145 x 135 mm (H x W x D) and can be operated in temperatures from –40 to +65° C with relative humidity of 0 to 100% and pressures from 700 to 1300mbar. Approvals include UL, CSA, ATEX and the CE mark.
