Intox DMT®

The Intox DMT, an advanced evidential desktop breath testing instrument, was the first to integrate a breath alcohol testing instrument with a powerful embedded computer with graphics touchscreen. The unit combines a judicially accepted analytical system with a customizable user interface, and has the fastest signal processing in the industry, allowing test results to be displayed in real time, without any delay.

The Intox DMT-G includes the same features, but adds an internal housing and connections for calibration with gas standards. The dry ethanol gas tank connects easily and securely inside the compartment.

  • Multi-filter infrared spectroscopy
  • Real-time graphics display of breath profile and alcohol curve during a subject test
  • Color printout of breath profile and alcohol curve on the test ticket.
  • Touch-screen graphics display
  • Real-time critical instrument data such as internal voltages, temperatures, etc. (locally or remotely)
  • On-screen adjustment of internal voltages without having to open the unit. This can be done from remote locations.
  • Local access to previous tests without special software
  • Powerful embedded PC
  • Multiple USB ports to accommodate peripherals
  • Windows media player audio and video capabilities
  • Modular design for secure but quick access for service.
  • Adapts to both transportable and fixed-site testing
  • Fastest signal processing in the industry (breath test results are displayed in real-time without any delay).


ApprovalsNHTSAListed on the Conforming Products List for Evidential Breath Measurement Devices by the National Highway Traffic Safety Administration of the United States Department of Transportation {NHTSA (U.S. DOT)}
Analytical SystemInfrared AbsorptionInfrared Bench with filtering at 3.37, 3.44, and 3.50 micron wavelengths
OPTION:  Electrochemical Sensor (Fuel Cell)The Intox DMT-F includes the optional addition of a Fuel Cell sensor to provide dual technology capabilities. Contact Intoximeters for further details.
Measurement Range0.000 to 0.600 %BrAC (or equivalent)The Intox DMT instrument is designed to offer a range of measurements that our customers commonly encounter when performing breath alcohol testing. The instrument is capable of performing analysis when even the most extreme blood alcohol levels found in living humans is encountered.

A wide variety of units of measure are available in the instrument to meet the needs of individual testing programs around the world.

Exceeds OIML R-126 recommendations for measurement range.

Accuracy and PrecisionHighly accurate and precise evidential grade resultsDesigned to meet or exceed both NHTSA (U.S. DOT) and OIML R-126 recommendations for accuracy and precision.
Sensor SelectivityHighly specific for alcoholThe analytical bench of the Intox DMT features a long life grey body infrared source and filters at three wavelengths (3.37, 3.44, and 3.50 microns) to provide analysis that is highly specific to alcohol with a high level of stability and efficiency.
Sampling MethodFlow, Volume, BrAC SlopeEach breath sample is monitored to determine the appropriate time to capture a breath sample
Testing EnvironmentInstrument TemperatureThe instrument operating temperature is self regulated and monitored to assure that testing conditions meet sampling requirements.
Ambient TemperatureProvided the instrument has met its internal temperature requirements it can be used. Typical environments are in the range of 0 to 50 degrees C.
