Accurate and reliable results The hazardous substances in the air are collected using a suitable medium – such as activated charcoal, silica gel or molecular sieves. The sample is then analyzed in a laboratory with the aid of instrumental analysis. The sampling process is conducted either actively with a manual Dräger accuro or automatic Dräger-Tube pump X-act 5000, or passively via a diffusion sampler.
Suitable for complex cases The Dräger Sampling Tubes and Systems allow to identify and measure different substances even under difficult conditions. This applies especially to very complex mixtures of substances or cases in which several similar substances are present at the same time.
Advantages of passive sampling Low price since no additional sampling equipment is required Long-term sampling does not require any preparation of the room Low determination and detection limits Fluctuations of concentration are integrated into the measurement result Overview measurements as well as surveillance of limit values
Advantages of active sampling Accumulation of substances in large amount of air within short time Low determination and detection limits
The Dräger Polytron® 5700 IR is a cost effective explosion-proof transmitter for the detection of flammable gases in the lower explosive limit (LEL). It uses a high performance infrared Dräger PIR 7000 sensor that will quickly detect most common hydrocarbon gases. A 3-wire 4 to 20-mA analogue output with relays makes it compatible with most control systems.
The Dräger PIR 7000 is an explosion proof point infrared gas detector for continuous monitoring of flammable gases and vapours. With its stainless steel SS 316L enclosure and drift-free optics this detector is built for the harshest industrial environments, e.g. offshore installations.
Tailor-made for use in CBRN hazard situations: The gas-tight Dräger CPS 7900 provides excellent protection against industrial chemicals, biological agents, and other hazardous substances. Its innovative material qualifies the CPS 7900 equally well for civil emergency and disaster recovery missions as well as decontamination work.
