Common FAQ for Buying a Breathalyzer

Why Do You Need a Breathalyzer?

If your personal safety and safety of others is important to you, you will definitely go for a personal breathalyzer. Buying one can ensure avoiding consequences of intoxicated driving.

What Are the Differences between Personal Breathalyzer and Professional Breathalyzer?

What is BAC?

BAC is the abbreviated form of Blood Alcohol Content. Usually, it is mainly used as a metric of intoxication for medical and legal purposes. There are certain factors that affect BAC of yours-

  • Age– The more you get older; the effect of alcohol will be vivid in you.
  • Rate of Consumption– The rise of BAC depends on the consumption speed of alcohol.
  • Gender– Alcohol is water soluble. As women have lower water content in their body, they will result in high BAC percentage while having equal amount of alcohol of men. Besides, women have lower amount of enzymes in their stomach than men which can break alcohol faster.
  • Drink Strength– the BAC percentage will raise rapidly if you consume a drink with higher alcohol content.
  • Metabolism– As metabolic tolerance is dissimilar from person to person; the breakage of alcohol in different body will vary.
  • Body Weight– More body weight means you has more water in your body. As alcohol is water soluble, the BAC percentage in weighty people won’t get higher easily. Rather the slim people will get higher percentage.
  • Food Consumption– If you have alcohol in empty stomach, the BAC rate will be higher than a person who has consumed food before drinking.
  • Carbonation- Carbonated drinks, like champagne or sparkling water will increase the BAC rate of your body.
  • Emotional State- Yes, stress can slow down the absorption rate of alcohol in your blood. If you get a BAC test while you are stressed and emotionally week, the rate will be higher. Take the test again when you are calm down. You will definitely find a surge in the rating.

How Often You Should Calibrate Your Breathalyzer?

Your breathalyzer should be calibrated. Make sure you calibrate it once a year or after 300 uses. The breathalyzer with fuel censor remains perfect for thousands uses, but you should calibrate it in each year.

Is It Safe to Drive When Your Breathalyzer Shows Negative?

Definitely not! If you are using professional breathalyzer, you are getting almost accurate result. If it is showing high BAC rate, you should never think of driving. Why to risk your life and reputation?

How Does a Breathalyzer work?

It is a well-known fact that breathalyzer can measure the level of alcohol content in your blood which is crucial to determine whether you can drive or not. But, how does the device work?

Usually there are three types of breathalyzer available at market-

  1. Semi-conductor Oxide Breath Analyzers– These are one of the most low cost device and also consume less power. But, the problem with these devices is that it doesn’t give you the most accurate level. It contains an ethanol censor, but often there are some drinks or food elements may contain ethanol. Therefore, it may give you false reading.
  2. Fuel cell Breath Analyzers– This type of breathalyzer comes with electrochemical fuel which uses chemical components to oxidize alcohol from the breath sample and generate an electric current from that oxidization process. Higher alcohol level in your blood means the device will generate more electric current.
  3. Spectrometer Breath Analyzers– It analyzes the molecules as they react to the infrared light. This process provides the most accurate result. But, these are large devices and also quite expensive ones.

Steps of Getting Appropriate Result on Breathalyzer

You get so much information about breathalyzer. But, if you are using it for the first time, you may get a bit confused. To get the accurate result, you should follow the following steps-

  • Before using it, breathe at normal rate.
  • When you are at normal body temperature, you should use the breathalyzer. If you have just worked out, or have been in extreme cold or heat, you have to wait till your body temperature matches the room temperature. Then you can start testing.
  • If you have just donated blood, you should allow the device to get greater reading range.
  • Every breathalyzer must be calibrated once a year, but that depends on the frequency of using the device. If you use it randomly, you should calibrate it every six months.
  • When the breathalyzer is not in use, you should keep it inside the protective case, so that the device won’t get contaminated by the environmental gases.

To get more information on how to take care of your breathalyzer and more details on using the device, you should go through the user manual provided by the manufactures.
