Frequently Asked Questions About Digital Breathalysers

What is a digital breathalyser?

A digital breathalyser is an electronic device that measures the amount of alcohol in a person’s breath and provides a reading on a digital display. It is commonly used for personal alcohol monitoring, workplace alcohol screening, and professional testing.

How does a digital breathalyser work?

A digital breathalyser measures the alcohol in a person’s breath using an internal sensor. When you blow into the device, it analyses the breath sample and displays an estimated alcohol reading on the screen within seconds.

How accurate is a digital breathalyser?

The accuracy of a digital breathalyser depends on the sensor technology used. Fuel cell breathalysers are generally more accurate than semiconductor models and are often recommended for professional or workplace use. Evidential breathalysers (police grade) are the most accurate and recommended for workplace confirmation testing.

What is the difference between a personal and professional digital breathalyser?

A personal digital breathalyser is designed for occasional home use, while a professional breathalyser is built for frequent testing and may offer higher accuracy, faster results, and data storage for workplace alcohol testing.

How long should I wait after drinking before using a digital breathalyser?

It is best to wait 15 to 20 minutes after your last alcoholic drink before taking a breath test to avoid residual alcohol in the mouth affecting the reading.

Do digital breathalysers need calibration?

Yes, digital breathalysers should be calibrated regularly to maintain accuracy. Depending on usage, most manufacturers recommend calibration every 6 to 12 months. Many of the personal breathalysers including the AL7000 and the Alcodigital Platinum have replacement sensors that make recalibration easy. 

Are fuel cell breathalysers better than semiconductor breathalysers?

Fuel cell breathalysers are considered more reliable because they are specifically designed to detect alcohol. Semiconductor sensors are more affordable but may be affected by other airborne substances.

Can a digital breathalyser be used for workplace alcohol testing?

Yes, many digital breathalysers are suitable for workplace alcohol screening. Higher-specification evidential Draeger breathalyser models are often used by employers to support workplace safety policies and to confirm positive alcohol results obtained using rapid onsite drug and alcohol testing kits..

Can more than one person use the same digital breathalyser?

Yes, most digital breathalysers can be used by multiple people when each person uses a fresh disposable mouthpiece for hygiene and accurate testing.

How often can a digital breathalyser be used?

A digital breathalyser can usually be used multiple times per day, but frequent use without allowing the sensor to recover may reduce accuracy. Always follow the manufacturer's usage guidance.

Can a digital breathalyser tell if I am under the drink-drive limit?

A digital breathalyser can provide an estimate of your alcohol level, but it should only be used as a guide. The safest choice is always to avoid driving after consuming alcohol.

Can cold weather affect a digital breathalyser?

Extreme temperatures can affect performance. For the most accurate reading, use your digital breathalyser at room temperature and store it according to the manufacturer’s instructions.

Can I store a digital breathalyser in my glove box?

It is not usually recommended to store a digital breathalyser in your glove box for long periods. Extreme heat in summer and very cold temperatures in winter can affect the sensor and reduce the accuracy of the device. For the best performance, store your digital breathalyser in a cool, dry place and keep it in its protective case when not in use. If it has been kept in a cold or hot car, allow it to return to room temperature before using it.

Customers often ask practical questions before buying a digital breathalyser, especially around accuracy, maintenance, and everyday use. Here are some additional high-value FAQ ideas that could improve both customer trust and SEO on your page:

How often should I replace the mouthpieces?

Disposable mouthpieces should be replaced after each user to maintain hygiene and ensure accurate readings. Many digital breathalysers come with spare mouthpieces, and replacements can usually be purchased separately.

Can medication affect a digital breathalyser reading?

Some alcohol-based mouthwashes, sprays, or medicines can temporarily affect a reading. It is best to wait 15 to 20 minutes after using these products before taking a breath test.

How long does a digital breathalyser battery last?

Battery life varies by model. Some digital breathalysers use replaceable batteries, while others are rechargeable. Frequent use may require more regular charging or battery replacement.

Can I use a digital breathalyser the morning after drinking?

Yes, a digital breathalyser can be useful the morning after drinking, as alcohol can remain in your system longer than many people expect.

How quickly does a digital breathalyser give results?

Most digital breathalysers provide a reading within a few seconds after the breath sample has been taken.

Does smoking affect a breathalyser reading?

Smoking immediately before a test may interfere with the result. It is recommended to wait at least 15 minutes after smoking before using the device.

Can digital breathalysers detect drugs?

No, a digital breathalyser only measures alcohol in the breath. Drug testing requires a separate saliva, urine, or blood test kit.

How do I know when my breathalyser needs calibration?

Some digital breathalysers display a reminder message when calibration is due. Signs of poor accuracy or inconsistent readings may also indicate servicing is needed.

Is a more expensive digital breathalyser worth it?

Higher-priced digital breathalysers often use fuel cell technology, which can provide better accuracy, reliability, and longer-term performance than lower-cost models.

Can I travel with a digital breathalyser?

Most personal digital breathalysers are compact enough to carry in a bag or suitcase, making them useful for travel, but they should be protected from extreme temperatures.
