AlcoFind AF-100S is a high quality alcohol tester, designed for conducting large numbers of quick tests, preliminarily determining BAC of the tested persons. The digital alco tester does not require mouthpieces for operation, reducing maintenance costs, and ensures swift and hassle-free screenings.

The Alcohol testers are frequently used by:

  • UNIFORMED SERVICES – the police, city guards, or the military, for quick tests for breath alcohol content, e.g. during routine traffic control.
  • COMPANIES – to ensure employees' sobriety, a vital safety factor in a number of branches, especially considering the fact that it is the employer that is usually liable for possible damages caused by inebriated personnel.
  • MASS EVENT PROTECTION – for screening the persons entering the event grounds; passive mode of the digital breathalyzer allows to check carried in beverages for alcohol presence.

Key advantages of AlcoFind AF-100S digital breathalyser

  • Sensor type


    AlcoFind AF-100S is equipped with a very accurate electrochemical fuel cell sensor, offering high sensitivity, stable parameters, and very short warm-up, sample analysis and return to standby times.

  • Image sensor


    Calibration is recommended after conducting as many as 500 test, not less often than every 12 months. The user can set the alarm threshold at one of 5 available levels, from 0.1 to 0.5‰ (0.05 – 0.25mg/l).

  • LED indicators


    Screening results are indicated by colour LED lights. The alcohol content is signalised with precision far greater than those offered by inferior instruments. The number and colour of lights reflects the range within which the result is located, compared to previously defined threshold – 1 blue light indicates 0-20% set value, 5 blue lights – 81-100% value, while 3 orange lights signal alarming value of 151-200%

  • 3 PIR motion sensors


    The AF-100S high quality alcohol tester notifies the operator about its status (number of conducted tests, remaining time until due calibration, battery level, readiness, or sample collection) by LED light sequences. Additionally, to further facilitate the operation, the device was equipped with a flash lamp.

  • Very discreet


    The digital can work in one of two available modes – active, requiring tested person to blow air at the sensor, or passive, in which the screener collects samples automatically. Passive mode is useful in cases of screened individuals being unable, or refusing to take the test. It can also be utilised to screen liquids for alcohol content – the device collects vapours, e.g. from a bottle of beverage, in order to determine possible presence of alcohol.

  • Power supply


    The AlcoFind AF-100S alcohol tester is powered by a built-in Li-Ion 2000mAh battery, enabling operation time for up to 10 hours.

The AF-100S alcohol tester is a professional instrument, allowing to test large groups of people quickly and easily. Due to a high quality sensor and mouthpiece-free operation, it guarantees low maintenance costs and high efficiency.

Service and Warranty

Comment : My business partner recommened me the detective online store and also this particular model of breathalyzer. Let's be honest, there should be no tolerance whatsoever for people coming to perform their work duties under influence of alcohol and I decided to not be lenient anymore and started testing my team with AlcoFind. I definitely recommend to all business owners.
