Input/Output Devices

Keypad
The Intox EC/IR is compatible with virtually any PC AT-compatible keyboard.

Display
The Intox EC/IR display is a two line by twenty character vacuum fluorescent display. The display is:

• highly reliable - rated for a life time of 50,000 hours.
• very bright - 685 cd/m2 (or 200 fL)
• low power
• supports a large international character set

Printer
The Intox EC/IR incorporates a high performance thermal printer.

• 7.5 lines per second
• 150 dots/inch resolution
• Integrated paper handling system that requires no threading which means changing the paper roll takes seconds and their are no paper jams.
• Multiple text modes including compressed, double width and height, bold and reverse image.
• Large character set.
• Quiet
• No ink ribbons to change
• Available with heat and UV resistant paper for long-lasting printouts

External Printer
The Intox EC/IR can print to most IBM PC-compatible Centronix printer via the 25-pin printer port on the back panel of the instrument.

Audio
Built-in speaker

Bar Code and Magnetic Stripe
The Intox EC/IR supports a variety of PC-compatible devices

Internal Modem

• Hayes compatible
• 33.6 Kbps
• Enhanced AT commands

Other I/O
2 RS-232 serial communications ports
1 parallel port

UNIQUE FEATURES

• Parallel processing allows communications and analysis functions to be performed simultaneously
• Dual sensor utilizes the best capabilities of both electrochemical (EC) sensors and infrared (IR) detectors
• Fully automated test procedure
• Advanced self-diagnostic capabilities
• Automatic accuracy checks and calibration
• Capable of remote operation and remote trouble-shooting
• Stores multiple test protocols

Sensor
The fuel cell sensor generates a response that is proportional to the breath Alcohol Concentration. The response is linear and requires one point calibration. Multi-filter Infrared detector offers real time analysis of breath sample.

Accuracy & Precision
US DOT approved for evidential use. Meets and exceeds the federal model specification for traffic enforcement and Omnibus Breath Alcohol Testing.

Specificity
The fuel cell sensor is specific for alcohol. It does not respond to acetone or other breath substances.

Measurement Limits
The EC/IR can accurately detect breath alcohol levels between .000 - .400 BrAC.

Response Time
The instrument responds within 10 seconds on negative samples and within 30 - 45 seconds on positive samples

Sampling Rate
It can be used every 15 to 20 seconds when negative tests are encountered. After a positive test, depending on the amount of alcohol in that sample, the instrument may require up to a 2 minute wait before further testing can occur.

Drift
Instruments will maintain calibration (plus or minus .005 at the .100 level) for several months.

Calibration
Checks and calibrations should be performed with either a National Highway Traffic Safety Administration (NHTSA) approved wet bath simulator or a dry gas standard. Fully automatic calibration can be selected as an option with either a dry gas standard or wet bath simulator.

Environmental
Operates between 0° and 40° C.
