Alcotest 7110

Middlesex County NJ DWI Lawyer Explains the Draeger Alcotest 7110

Middlesex NJ Alcotest DWI LawyerDraeger Industries in Lübeck, Germany manufactures the Draeger Alcotest 7110 MK III-C. The State of New Jersey has adopted Draeger’s Alcotest 7110 as its preferred device by which to measure the blood alcohol content of suspected drunk drivers.

The Draeger Alcotest 7110 MKIII-C utilizes two different and independent systems for measuring BAC from a driver’s breath. The first system analyzes alcohol in breath samples through a technology called infrared spectroscopy (IR). The second system analyzes alcohol in the same breath sample utilizing electrochemical cell (EC) technology. The utilization of two technologies on the same breath sample (in essence, measuring the breath sample twice) is intended to provide the highest level of forensic and legal integrity.

Essentially, this means that the machine takes in exhaled air and then produces from this a reading for each of its components, the infrared spectroscopy reading and the electrochemical fuel cell measurement.  Each test must be administered with a separate mouthpiece and there must be a two-minute period between each test in order for the machine to recalibrate itself.  These four numbers are then placed into an algorithm that assesses their accuracy. The resulting outcome of the formula established whether or not the BAC of the driver is “over the limit”.

However, the Alcotest is often criticized as a “delicate” machine, and the administering officer must adhere to slight technicalities when administering the dual tests of the Alcotest. For example, as was established in State v. Chun, a case that confirmed the legal use of the Alcotest by New Jersey law enforcement, the officer must observe the suspect for twenty minutes prior to administering the test. This is to ensure that the suspect does not do anything that in any way may skew the results of the test. Such acts can include chewing gum, washing of mouth, burping, or eating.  Furthermore, radio wavelengths may affect the test readings as well.
