Stop Nuisance Odours from Becoming Life-Threatening

Nuisance odours can turn into life-threatening hazards, particularly where substances such as hydrogen sulphide and ammonia are involved. Ideal for use in the waste and water industry and offering a low cost of ownership, the ChemLogic range of colorimetric gas detection systems from Draeger (Germany) are designed to detect low levels of toxic and corrosive gases at the odour stage. Detecting in parts per billion (ppb), these continuous monitoring systems also require no calibration.

Featuring built-in data logging to record concentrations over time, they are ideal for perimeter monitoring applications and can also be used to predict breakdowns or to identify reduced efficiency in stack scrubber applications for example.

Hydrogen sulphide, for example, is as poisonous as hydrogen cyanide and often found in sewers and where organic matter is purifying. Although it has a pungent odour there is a rapid accommodation to its smell which significantly increases the danger of exposure. The ChemLogic is able to monitor H2S in ppb, well before it causes headache, vertigo or collapse and eliminating the immediately lethal effects of exposure to high concentrations.

Featuring advanced optic technology, the ChemLogic Series forms part of a new generation of interference-free, low maintenance, continuous monitors. Offering more flexibility in use than previous systems, it provides increased measurement security via fibre optics.

The ChemLogic 1 is a single-point detector. For those applications requiring greater monitoring capability, the ChemLogic 8 has eight detection points and an optimised flow that is able to draw samples twice as fast as other multi-point systems at 250-300ft 2.5 LPM.

The use of fibre optics enables improved focus and direction of light as well as a better signal to noise ratio. In addition, by removing the use of O-rings, the system ensures a cleaner interface between the optic, sample stream and tape.
