What is a DataMaster DMT?
The DataMaster DMT is a scientific instrument designed to analyze a sample of a person’s breath and determine the Breath Alcohol Concentration (BrAC) in that sample. • The DataMaster analyzes the breath sample using infrared absorption spectrometry.
What is the number of infrared wavelengths in DMT?
Because chemical bonds absorb IR energy differently at various wavelengths, the DMT machine looks for ethanol by using 3 IR filters at 3 specific wavelengths (3.37, 3.44, and 3.5).
What is the internal quartz standard?
An internal quartz standard checks the calibration of the instrument with every test. → Wet bath external simulation is a standard feature. → Dry-gas, with automatic barometric pressure compen- sation is optional. The DMT can be connected to a network using high-speed modem or Ethernet.
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.
What is the result range of the Intoxilyzer 8000?
The instrument will display CONTROL OUTSIDE TOLERANCE, abort the test,printan * by the test result in the results section of the report, and print *CONTROL OUTSIDE TOLERANCE. The acceptable range for the 0.080 g/210 L dry gas standard is 0.075 to 0.085.
How does the instrument report the result of the breath samples?
Infrared- The IR sensor continuously monitors the breath sample to determine the exact moment to introduce the sample to the electrochemical portion of the instrument. The IR sensor is also used to detect residual alcohol in the mouth.
What is dry gas target?
The strip also states the “Dry Gas” target which is the known sample the machine tests before and after the subject blows in order to verify the machine is properly calibrated and working.
What is the tolerance range for the control test?
0.077 to 0.083 g/210L
The control tests are automatically conducted during the breath test sequence. The Dry Gas Standard is used to conduct control tests during the breath test sequence. The gas concentration used is 0.08 g/210L. The acceptable range for the gas analyses is 0.077 to 0.083 g/210L.
How does the Intoxilyzer 9000 work?
The Intoxilyzer 9000 uses infrared spectrometry (IR) to measure alcohol in breath. IR analysis is the absorption of infrared energy by alcohol molecules in breath. It measures the absorption of radiant energy by a substance. IR is a lower frequency wavelength than the visible light that we see.
Does the Intoxilyzer 8000 detect acetone?
In this case, both the Draeger Alcotest® 6810 and Intoxilyzer® 8000C performed as would be expected for an individual with elevated acetone. The Alcotest® 6810 is a fuel cell device that does not react to acetone and, as such, any ethanol detected is unaffected by the presence of acetone.
How does the Intoxilyzer 8000 work?
The Intoxilyzer 5000 and the newer 8000 machines work by exposing air in a sample chamber to infrared light. An emitter produces a known amount of infrared light which passes through the sample chamber to reach a sensor at the opposite end.
What is the Datamaster DMT?
The DataMaster DMT is basically an updated version of previous DataMasters, containing numerous new features and updates. To improve the device’s usability and functionality, it is equipped with a large display screen with a Windows-based interface.
Why is the Datamaster DMT not printing my alcohol result?
– If a status message appears on the display and/or printout or the officer indicates the test was an “INCOMPLETE”or “ REFUSAL”, the DataMaster will not print out a subject’s alcohol result. In addition, the graphic display will not include the alcohol scale. Operating the DataMaster DMT
How does the Datamaster DMT measure BAC?
The DataMaster DMT uses infrared spectrophotometry, or an infrared light beam that measures an individual’s BAC from his or her breath, as alcohol, scientifically called Ethanol, absorbs infrared light. The device captures the sample, which is the air that an individual breathes out, as infrared light enters the machine’s sample chamber.
Does the Datamaster DMT work with Iowa DOT TRACS?
– The DataMaster DMT works in a similar fashion to the DataMaster cdm in how it interfaces with the Iowa DOT TraCS program. – Utilizing the TraCS interface in no way effects the analytical integrity of the DataMaster DMT. The interface is simply a tool to permit data sharing between the DataMaster and the TraCS software.
