Lifeloc designed and manufactures the Lifeguard breathalyser in the USA. Lifeloc breathalysers are now AS3547 certified.

Lifeloc is a premium fuel cell breath alcohol tester that provides accurate and reliable measurement of Breath Alchohol Content (BAC) for those concerned about alcohol intoxication in themselves or others.

Popular testing uses include workplace and personal testing for reliable and accurate results.

Lifeguard uses the same Platinum Fuel Cell technology that powers this globally recognised law enforcement equipment. Lifeloc breathalysers are used in over 35 countries and by many law enforcement agencies, for very good reason - they are exceptionally reliable and accurate!

Key Product Features:

  • Alcohol Specific. LifeGuard is always and only alcohol specific. Common semiconductor devices can give positive readings even when no alcohol is present.
  • BAC Management. LifeGuard charts your last three test results so that you can visually confirm whether your Blood Alcohol Content (BAC) is rising or falling, increasing your awareness of how alcohol affects your body.
  • Reliable. The combination of long working life, BAC management, alcohol specificity and high accuracy adds up to a device that can be trusted to perform.
  • Accurate. LifeGuard uses the same fuel cell technology that Lifeloc put into their law enforcement breathalysers.
  • Easy to Use. LifeGuard prompts you with easy to understand icons on a high resolution screen – making it easy and fast to get BAC readings
  • Electrochemical Fuel Cell
  • Convenient menu
  • Ease of Use in the Field. With just two buttons, the Lifeguard easily allows the operator to:
    • Capture breath samples
    • Recall previous tests in seconds.
    • With extra large buttons, users can operate the lifeguard whilst wearing gloves.
  • This unit is recommended for law enforcement and healthcare applications.

Great Accuracy

  • The Lifeguard uses a platinum electrochemical sensor (fuel cell) – the standard in police issued breath testers.
  • The long term stability of the sensor means you can count on accurate results year after year.*


  • Lifeloc breath alcohol testers are warranted to be free from defects in workmanship and material for one year (from the date of purchase).
  • It is recommended that only qualified technicians perform maintenance of any breath alcohol tester.

* All breath alcohol testing devices require periodic maintenance and calibration to ensure proper working order. Industry best practice is every 6 months for workplace testing.
