Gas detection for water and waste applications

Edited by the Processingtalk editorial team May 28, 2008

Ideal for use in water and waste applications, the Draeger Polytron 3000 is an intrinsically safe gas detector for monitoring gases such as hydrogen sulphide, oxygen, chlorine and ozone

Reliable and easy to use, it features innovative "plug and play" technology and, with yearly maintenance intervals, can halve the costs usually associated with traditional servicing requirements.

Comprising two components known as a "docking station" and a transmitter, the Polytron 3000 enables 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 135mm (H x W x D) and can be operated in temperatures from - 40 to +65C 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 extensive Draeger range of gas detectors.

It is suitable for use under 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).
