Maintenance and calibration of electronic breathalyzers

Calibration of electronic breathalyzers is absolutely necessary and essential to ensure reliable and accurate measurements over time. As with any precision instrument, electronic breathalyzers, alcohol ignition interlocks (EI), and breathalyzers must be monitored and inspected periodically every year. A well-maintained and regularly calibrated device contributes to improving prevention and, above all, guarantees everyone safety! 

Electronic breathalyzers

With more than 30 million alcohol tests per year, Dräger is the undisputed world leader in alcohol testing. Dräger electronic breathalyzers are rapid and hygienic and guarantee reliable and accurate results. In many countries, law enforcement agencies use the devices of the Alcohol Test series daily for roadside checks.

Ignition Interlock Device (IID)

Each time the car starts, the driver must blow into the breathalyzer. If the result is negative, he has 5 minutes to start the engine. In case of a positive value, the driver has a second test. If it is still positive, the engine is blocked for half an hour.

These devices must therefore be extremely accurate not to immobilize the vehicle unnecessarily. For this reason, these devices require periodic checks and regular calibration to ensure the operation and accuracy of the measurements. The French legislation has fixed the number of verifications at least twice a year.

Breathalyzer calibration

GazDetect offers a complete range of standard gases for electronic breathalyzers calibration. The mixtures are made by AirProducts and meet the strictest standards. They are mixed by gravimetry, usually applying the principles of the ISO6142 standard, and are compatible with all models offered by major manufacturers in this sector.

Ethanol (C3H60) standard gas cylinders are made of aluminum, single-use (disposable cylinders) with precise and known concentrations. They guarantee precision, optimal stability, and maximum shelf life.

Two types of standard gas cylinders are available:

  • Aerosol cylinders require an ethylometric adapter use, and they are designed for gas tests for anti-starting control.
  • The classic cylinders with flow regulators are available in two sizes: 34L or 110L, according to the needs of standard gas.
