Cutting the cost of continual gas detection
May 1st 2009

Monitoring of toxic gases and oxygen is necessary for cvompanies with more than 5 employees to comply with the new CoSHH Regulations.Draeger's Polytron 3000 offers continuous monitoring while having low cost of ownership

The Draeger Polytron 3000 is an intrinsically safe gas detector for the continuous monitoring of toxic gases and oxygen in ambient air. Featuring new 'docking station' and transmitter technology, it offers a 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 (Cl2), 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 precalibrated sensor, it also features digital temperature compensation and an LCD display.

Weighing 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.

The Polytron 3000 is the latest addition to the Draeger range of gas detectors. It is suitable for use under the new CoSHH Regulations which require any organisation with more than 5 employees to monitor for asphyxiant gases such as nitrogen, helium and argon. As these gases are colourless and odourless, it is difficult to prevent or adequately control exposure without measuring the oxygen content of air.

(Oxygen is not, in itself, flammable but it can aid combustion and increase the risk of explosion. Oxygen deficiency affects brain function, whereas oxygen enrichment causes an increase in the metabolic rate – both of which can be dangerous in the working environment.) Draeger Gas Detection division offers products, services and system solutions for all encompassing toxic, flammable and oxygen detection, flame detection and design, build, commission and maintenance of fire and gas detection systems for protection of personnel and assets.
