DUI awareness and the terrible consequences of drunk driving has led to a recent increase in purchases of alcohol breath testers, commonly known as breathalyzers. Unfortunately, when it comes to understanding the differences between each brand and model most consumers do not have an idea where to start.

Here's what you should know about Breathalyzers To Make An informed decision

1) How A Breathalyzer Works and the legal limit

When you blow your breath a breath test ignores a sensor that interprets the level of alcohol and a formula is applied to the blood alcohol content (BAC) to extrapolate.

The "legal limit" in all 50 states is 0.08 BAC. At 0.08 BAC or above you are considered legally intoxicated. But beware. Many people are affected at .04 BAC (and below), and you can be charged with "Driving as doubtful ' at .04. Although a violation may still be too costly and lead to a number of significant aggravation. More importantly, you yourself and others at risk, even at these lower alcohol concentration in the blood.

2) types of sensors

The sensor is the component within a breath test that reads and interprets your BAC. For personal use there are two types to consider, fuel sensors and semiconductor sensors. In the Breathalyzer is used correctly each of these types of sensors will yield accurate results to about 1.5 x is the legal limit.

At higher blood alcohol levels (well above the legal limit) fuel cell sensors more accurate results. Fuel cell breathalyzers are more expensive to make usually costs between $ 450 and $ 1500.

Semiconductor sensors are more economical to manufacture which helps to keep down the total cost of the Breathalyzer. Depending on the quality of the sensor and other features, quality breathalyzers with semiconductor sensors cost between $ 55.00 and $ 300.00.

3) Calibration

When you first receive your new bladder pipe the sensor is factory calibrated for accurate measurements to it. Over time, residue will accumulate on sensor that uses imprecise measurements. All breathalyzers, except the two models listed below, require periodic recalibration. Usually this that shipping them back to the manufacturer for 6 to 12 months for recalibration. The cost for this service runs between $ 20.00 and $ 50.00 plus the cost of shipping.

Currently there are only two breathalyzers on the market that do not require factory recalibration. They are the AlcoMate AlcoMate Premium and Prestige. Both have breathalyzers "the user Changing "sensor modules. The consumer can easily replace the sensor module in minutes (less than 30 seconds in the AlcoMate Premium) restoration of the Breathalyzer to" factory new " calibration.

Avoiding the inconvenience and cost of the reassessment to AlcoMate Premiun and worth serious consideration AlcoMate Prestige.

4) nozzle intake (Active) vs. Blow-Over (passive)

All breathalyzers require that the subject provide a breath test on the sensor for testing. The most accurate method is through a mouthpiece directly attached to the Breathalyzer. This ensures that the breath sample is not "contaminated" with air, smoke, etc. from the environment. .

The other method is called as "blow-over or passive testing. The subject puts their mouth about an inch of breathing intake and receiver blows strong. Done correctly this method is accurate results. However, air may enter the environment from the blow pipe making less than accurate results.

The benefit to the "blow-over" type breath test is useful to parties and social gatherings where several people are tested, because no direct contact er with the mouth and no need for mouthpieces to change.

5) Style

Breathalyzers designed for personal use will be either hand held or keychain style. We already discussed hand-held "Mouthpiece" vs. "blow-over (passive) designs. There are also several breathalyzers on the market designed to fit on your keychain. Most, except BreathKey by Omega Point Systems are strictly novelty items. The BreathKey is the only model that is FDA certified and keychain is worth considering.

6) Price

For personal use quality breathalyzers cost between $ 55.00 and $ 225.00. In most cases, the higher the price, the better the product (accuracy, features, etc). Breathalyzers costs less than $ 50.00 are generally gadgets - highly inaccurate and without digital readouts. Do not waste your money.

7) Approvals

Each blow pipe worth considering, the FDA (Food and Drug Administration) approval. This essentially means that the FDA tested and it does what it says that the product in the literature. Other approvals such as the DOT (Department of Transportation), NHTSA (National Highway Traffic Safety Administrations) and the U.S. Coast Guard approval to confirm that the accuracy levels reported by the manufacturer consistent with their findings.

A breath test is a valuable personal design that can help you or someone you're with the right decision when it comes to alcohol and driving.
