Alcohol breathalyzer and drug testing

The advanced design of the DA3820 and DA5820 portable breathalyzer from Dräger allows professionals to quickly and easily perform breath alcohol measurements. The testing process through these devices is designed for hygienic use and provides highly reliable results. These devices can also monitor alcohol concentrations in ambient air (passive method) without using mouthpieces.

The Dräger DA3820 and DA5820 breathalyzer devices use the same sensor technology as the professional devices Dräger provides to the French police professional breathalyzers which carry out 30 millions of breath alcohol tests per year.

An ignition interlock device, or IID, is a regulated unit used for public transport. More and more buses that carry children - including school buses - have to be equipped with interlock breathalyzers worldwide. This regulation tends to extend to every bus. Besides, more and more companies are using this technology for their vehicles.

Alcohol interlock systems are automatic systems that require drivers to blow into a breathalyzer fitted inside their car. They can be adjusted to fit in different limits - according to any country legislation - but generally the vehicle can only be started if no alcohol is detected. Experts for transport safety have hailed this technology as a major component in reducing road deaths.

In many countries personal single-use breathalyzers are now disputed because of their ethanol reagent toxicity. Its disposal has to be performed aside from the classical recycling circuits. This matter does not arise for electronic breathalyzers as they are reusable (except for the plastic-made mouthpiece). They only require a calibration every six months in order to get constant accurate measurements.

Ethanol (C3H6O) calibration gas cylinders are made of aluminum. These disposable cylinders are filled with precise and known concentrations (usually 260 ppm). The calibration gas cylinders are gravimetrically mixed under the ISO6142 standard and ensure accuracy, stability and maximum shelf life.

In addition to our electronic alcohol breathalyzer range, we also offer drug test devices for the following substances: cocaine, opioids, cannabis, amphetamines and methamphetamines. This system is composed of a saliva drug test swab unit and a cassette filled with reagent liquids.

The testing time is set between 3 and 5 minutes depending on measurements sensibility. Once a substance is not detected, a line clearly displays facing the category. This kind of device is certified as a medical unit in the EU - 98/79/IEC regulation – and can be used for professional applications.
