If in doubt then do not drive, the risk is not worth it. Alcohol can take up to an hour to be absorbed into the blood stream meaning your BAC can rise for up to an hour after your last alcoholic beverage. A good way to know if you BAC is still rising or falling is to re-test yourself at 5 minute intervals.
Make sure that you are using alkaline batteries. Carbon batteries may not have enough power to start the unit up. Also be conscious of rechargeable batteries as some have different voltages.
Errors can happen for several reasons such as:
The battery power is too low to conduct a test.
Your sensor has alcohol build up and requires calibration.
Flow errors. Restart the unit and blow consistently through the mouthpiece.
If you are unsure then please contact us.
Smaller amounts of alcohol (1-2 standard drinks in an hour for example) may be processed and eliminated by the body quickly. Factors are dependent on individual constitution however so this is not necessarily the case. Your BAC will only continue to rise once your body can no longer process the amount of alcohol consumed. ie: past saturation point.
When you first turn your breathalyser on it will need to warm the units sensor up to approximately the same temperature as your breath, which is around 34 degrees celsius. Times will range from 5 – 45 second depending on the quality of sensor that you have purchased. This needs to happen to ensure accuracy of the reading. If the warm up time becomes very slow then this is an indication that there is residue alcohol build up on the sensor and it is time for recalibration.
Breathalyser sensor technology has advanced from purely semi-conductor to the use of electrochemical sensors as well in recent time. Quality electrochemical (fuel cell) sensors are more precise and hold their accuracy substantially longer than semi-conductor sensors. They are also more expensive however. That being said good quality semi-conductor sensors still have fairly high accuracy and will last at least 50 tests / 9 months before requiring calibration.
Few people understand the variables involved in how your body processes alcohol. There is a common misconception that I can have x number of drinks and be safe to drive. Here is a little interesting info:
The number of drinks. The more you drink, the higher the BAC.
How fast you drink. When alcohol is consumed quickly, you will reach a higher BAC than when it is consumed over a longer period of time
Your gender. Women generally have less water and more body fat per pound of body weight than men. Alcohol does not enter fat cells as easily as other cells, so more alcohol remains in the blood of women.
Your weight. The more you weigh, the more water is present in your body. This water dilutes the alcohol and lowers the BAC.
Food in your stomach. Absorption will be slowed if you’ve had something to eat as the alcohol will have less direct contact with the stomach lining.
We stock a full range of additional mouthpieces. You can order these through the site by going to the PRODUCTS page. Your unit will generally come standard with either 3, 5 or 6 pieces. All mouthpieces can be reused but please ensure that you keep them hygienically clean and that the airway remains clear. Mouthpieces are dishwasher friendly.
It is in fact more likely than not for two people who have consumed the same amount of alcohol, in the same amount of time, to have two different readings. BAC content is affected by gender, weight, age, metabolism, food and liquid consumption (to name a few). Results will also change from one day to the next with the same individual. This is why it is so important to have a breathalyser to test yourself. No breathalyser = no certainty.
Personal breathalysers are designed to help individuals understand their Breath Alcohol Content. As technology moves ahead they are being used increasingly from a personal well-being perspective. Certain latest model breathalysers enable functionality such as the tracking, graphing and averaging of alcohol consumption over time.
Some individuals choose to use breathalysers to determine whether or not it is safe for them to drive. All Breathalysers Australia’s breathalysers are for the purposes of indicative testing only. They cannot dispute the results of an official test and they cannot be used as evidence in a court of law. Neither the manufacturer, distributor or retailer will be held responsible for inappropriate use of any Breathalysers Australia products.
