How does the Intox EC IR II work?
Intox EC/IR II- The instrument collects a sample of breath through which an infrared energy beam is passed. At the designated time a portion of the breath is introduced to the fuel cell and a result is calculated. The IR sensor is also used to detect residual alcohol in the mouth.
What is EC IR?
Louis, Missouri. EC stands for electro-chemical and IR stands for infra-red. These are two very different methods of measuring ethanol. The infra-red method relies on the absorption of infra-red light by alcohol in the sample chamber which is noted by a detector at the opposite end of the chamber.
How do the numbers on a breathalyzer work?
The numbers are the measure of your blood alcohol concentration (BAC). This is determined by when you blow into the breathalyzer and it evaluates the levels of alcohol in your breath. In most states, you are considered legally intoxicated when your BAC is . 08 percent.
What is the most accurate test to determine BAC?
Blood tests generally produce more accurate results than breathalyzers and other breath tests. Blood tests directly measure the suspect’s actual BAC. Breath tests only indirectly measure someone’s BAC. Blood tests are also less susceptible to environmental factors that can skew the results.
Does a Breathalyzer measure BAC?
The Breathalyzer, the most famous portable device to test breath alcohol content, was invented in 1954. Alcohol breath-testing devices use the amount of alcohol in exhaled breath to calculate the amount of alcohol in a person’s blood, also known as blood alcohol concentration (BAC).
How accurate is a BAC blood test?
Blood alcohol tests are very accurate in determining BAC levels, but in some cases, the results may be misleading. These cases may involve: People with diabetes or high blood ketones.
How accurate are BAC tests?
The results of the test may be used as evidence of an over-the-limit blood alcohol level, but many factors can affect the accuracy of a breath test. In fact, peer-reviewed studies have shown a 50 percent margin of error when comparing breathalyzer results to actual blood alcohol content.
What is an Alco Sensor?
The Alco-Sensor IV is an evidential grade handheld breath alcohol tester, providing a simple, accurate and economical method of determining a subject’s breath alcohol concentration with evidential grade accuracy. It is the most widely used breath testing instrument today.
