Question-How long does alcohol take to leave your system ?

How long does alcohol stay in your system depends on many factors including :
-how much alcohol was consumed
-whether the alcohol was consumed with food or on an empty stomach
-the body weight of the person cosuming the alcohol
-whether you are male or female (generally males process alcohol faster then females as their livers are usually larger)
-your age
-your metabolism including how effectively your liver enzymes process & clear alcohol
-whether you are a regular drinker or an occaisonal drinker
-the type and stength of the alcohol consumed
-how well your liver is working
-whether you are taking any medication
On average it takes the body about one hour to break down one unit of alcohol. However this can vary hugely from individual to individual depending on the above factors.

Question -What is the accuracy of the digital breathalyzers ?

This depends on the model of breathalyzer that you are looking at. The latest model digital breathalyzers that we sell are all highly accurate if used according to the manufacturers instructions. For example for a professional digital breathalyzer such as the Alcodigital Platinum Fuel Cell Digital Breathalyser the accuracy is ±0.005 %BAC

Question- Will the breathalyzers detect alcohol the morning after ?

If the alcohol levels in your blood are still at a level that can be detected by a breathalyzer test then the breathalyzer will detect this. The rate at which alcohol is cleared from the body after a heavy drinking session varies from individual to individual depending on body weight , sex , liver function, and whether the alcohol taken with food or not and many other factors. You may well find that you are over the legal limit the morning after a heavy drinking session the night before, even if you feel fine.

Question -Which is the best home breathalyzer ?

We received this question recently:'My teenagers have just passed their driving test & are borrowing the car. I want to make sure they are not drinking and driving when they are going out in the evenings. They have promised they won't but I know they are susceptible to peer pressure and I want to be sure. Which breathalyzer would you recommend ?'

Answer As they are young inexperienced drivers you probably want to operate a zero tolerance to drinking alcohol while driving in this situation. Look at the single use breath alcohol detectors. Select the zero tolerance sensitivity if you want them to abstain completely which would be our advice. Click here to see single use breath alcohol detectors. Alternatively any of the digital breathalyzers that we supply are suitable for screening in this situation. Knowing you are going to test them will help them to resist the peer pressure as they know they will lose their car privilege if they test positive.

Question-Which breathalyzer is the best for the money ?

We receive this breathalyzer question on an almost daily basis:.I am looking for a digital breathalyzer for my own personal use. I need it to be accurate & reliable, and I do not want to spend more than I need to. Which breathalyzer is the best for the money ?
Our answer: As the choice of breathalyzers for personal use has increased this has made choosing a breathalyzer more difficult for the consumer. In our opinion the latest model DA5000 digital breathalyzer still offers the best value for money for the following reasons:
-Excellent accuracy
-Reliable breath testing in regular use
-Excellent value for money at just over £40
-Clip in clip out changeable sensor module-means the breathalyzer does not need to be returned for servicing you simply order a new sensor which is simple to install.
-1 year warranty
-comes with presentation box, battery, user manual, 6 mouth pieces & carry case with strap.
-CE RoHs Certified

Question-How often should my digital breathalyser sensor be changed ?

This is a very common question that we are asked at least five times per week as many of the digital breathalysers now have clip in clip out sensors that you replace yourself. The advantage to this is that the breathalyser does not need to be sent back to a service centre for re-calibration.
Answer The current recomendations are that to maintain the accuracy of the readings, the sensor in your digital breathalyser should be replaced with a new one every 200 tests, or every 6 months if the breathalyser is not being used this much.

Question-How should my breathalyser be stored and does it affect the accuracy ?

Answer: We are constantly astounded by the treatment some of our digital breathalysers receive. Many are stored in glove boxes of cars which is not ideal. The problem with storing the breathalyzer in the glovebox is the extremes of temperature that can be encountered inside the cars glove box. In winters the overnight temperature may be well below freezing and in summer the temperatures inside the car can be extremely high.
Ideally it is best not to store the breathalyser inside the car but to keep it in a bag or briefcase that you remove from the car , particularly at times of extreme cold of heat as the accuracy of the breathalyser can be affected if it is stored in extreme temperature variations.

Question-Which is the most accurate breathalyzer on the market in the UK ?

The most accurate breathalyser currently on the market in the UK is the Draeger evidential breathalysers which are similar to the ones the UK police use.

Question- Which is the most accurate personal breathalyzer you stock ?

The most accurate of the breathalyzers is the Alcodigital platinum fuel cell breathalyser. High accuracy and specificity for alcohol (±0.005 %BAC at 0.050 %BAC equivalent)

Question-Which is the best breathalyzer to buy for Scotland ?

The main thing to remember is if you are buying a breathalyser to use in Scotland make sure the alarm is set off to go off at the new lower limit in Scotland of 0.05% BAC or 50mg per 100ml BAC. If you are using a disposable breathalyser then you need to have a 0.05% BAC one for Scotland

Question-Can you buy accurate breathalyzers in the UK ?

This one is easy to answer. Yes the technolgy has moved on in the last few years, and there are now lots of affordable accurate breathalyzers to choose from, including the single use breathalyser kits, which are a great option, if you only want to test occasionally.

Question-Can you test for alcohol in urine ?

Question What's the difference between a standard and a professional breathalyser mouthpiece ?

Professional mouthpieces are longer and have a one way valve built in for greater accuracy. Standard breathalyser mouthpieces are a little shorter and have no valve. If you are buying mouthpieces for use with a breathalyser in a workplace or healthcare setting, opt for the professional breathalyser mouthpieces, as the one way valve prevents the subject being tested cheating, by sucking instead of blowing.
If you are buying mouthpieces for use with a personal breathalyser the standard breathalyser mouthpieces will be fine as you are unlikely to cheat yourself.

Question-What breathalyzer should I buy ?

The answer really depends on your requirements. If you have not found the answer in our breathalyser FAQ section above then give us a call on 01263 731 168 during our office hours or send us an e-mail and we will be happy to assist you.

Question-How much can I drink and drive ?

There is no simple answer to this question and our advice would be that you should not drink and drive. Alcohol is processed differently by different individuals and any alcohol in your system will impair your driving ability. The best & safest thing on a night out is to have a designated driver who abstains from drinking alcohol completely or use public transport or a taxi to get you back from your night out. In our opinion the UK current drink drive limit is far too high at 0.08 %BAC and should be brought down to the Scottish limit of 0.05% BAC.
