How does a breathalyser work?

A breathalyser is a device used to measure the amount of alcohol in a person's breath Breath Alcohol Content (BrAC), which correlates closely with their Blood Alcohol Content (BAC). A breathalyser test using either a digital breathalyser or a disposable breathalyser test kit can provide a non-invasive and quick method to estimate an individual's level of intoxication with alcohol, which is plays an important role in ensuring workplace safety , monitoring underage drinking or for personal use to ensure safety.

Key Points about breathalysers:

  • Accuracy: Different types of breathalysers have varying levels of accuracy. Fuel cell and infrared spectroscopy breathalysers are generally more accurate than semiconductor breathalyser sensors.
  • Breathalyser Calibration: Digital breathalysers need regular calibration to maintain accuracy. Some digital breathalysers now come with clip in clip out replacement sensors which makes recalibration simple. Breathalyser kits are single use and should be disposed of after use. They can not be recalibrated or re-used. 
  • Legal Limits: Legal BAC limits for driving vary by country and even within province within countries. For example the legal limit in Scotland is lower than in England and wales even though they are all part of the United Kingdom. Information on legal alcohol limits driving for UK and abroad.

A breathalyser test provides a non-invasive and quick method to estimate an individual's level of alcohol intoxication, which is crucial for workplace, schools and personal use to ensure safety.

  • Scotland: Lower limit of 50 mg per 100 ml of blood (0.05 BAC, 0.5 ‰)


What is a breathalyser, and how does it work?

A breathalyser provides a quick, non-invasive method to estimate blood alcohol concentration (BAC) using a breath sample. It’s ideal for ensuring safety in workplaces, schools, or personal use

Which breathalyser should I choose—disposable or digital?

  • Disposable breathalysers: Quick, low-cost, and suitable for simple employment alcohol screenings.
  • Digital breathalyser models: More accurate and often used in professional or evidential contexts. Higher price generally means higher precision

Can I use a digital breathalyser for workplace or evidential purposes?

Yes—UK Drug Testing offers Home Office-approved digital models with printer output, suitable for workplace compliance and evidential use. See Draeger breathalysers.

How do I use a disposable breathalyser?

Using a disposable breathalyser is simple. Most kits involve blowing into a tube for a set amount of time, then checking the colour change against a guide included in the kit. Full instructions are provided with every product.

How can I choose the right breathalyser for my needs?

Consider what you will be using the breathalyser for:

  • Casual or personal use vs. professional/workplace screening.
  • Digital, calibrated, Home Office–approved models are best for compliance.
  • Reach out via chat, phone (01263 731 168, Mon–Fri 8:30–16:30), or email for personalised help.

Can I reuse a disposable breathalyser?

No – these are single-use kits and should be discarded after use. For multiple uses, consider one of our digital breathalysers.

How do I use a disposable breathalyser?

Simply follow the instructions provided with the kit. Typically, you break the security seals, blow steadily into the tube for a set duration, and wait for the colour change to indicate your result.

How accurate are disposable breathalysers?

Our disposable breathalyser kits are calibrated to detect key alcohol thresholds and are manufactured to meet EU and UK standards. While they are not as precise as digital or police-grade breathalysers, they are accurate enough for general screening and personal safety checks.

What is a disposable breathalyser kit?

A disposable breathalyser kit is a single-use device designed to quickly and easily test for the presence of alcohol in your breath. It provides an indication of whether your blood alcohol level is above or below the legal limit for driving.

How should I store my breathalyser and sensor?

To ensure accuracy and longevity:

  • Store your breathalyser in a cool, dry place.
  • Avoid exposing it to extreme temperatures, moisture, or direct sunlight.
  • Keep the sensor clean and free from dust and debris.

Where can I buy the AL7000 Replacement Sensor?

You can purchase the sensor from authorised online retailers, including UK Drug Testing, or from other reputable sellers of alcohol testing equipment.

What should I do if any alcohol is detected?

Even a low alcohol reading on a breathalyser suggests impairment. We strongly advise that individuals do not drive or operate machinery if alcohol is detected—regardless of the level.

Can breathalysers detect drugs?

No—breathalysers exclusively detect alcohol. Drug detection in addition to alcohol requires saliva (oral fluid) drug and alcohol test kits. Saliva drug tests which detect drugs and alcohol are commonly used for detecting substances like Cannabis and Cocaine.
