Intoximeters RBT IV

  • SKU: 16-0145-00

The instrument monitors the subject's breath flow and volume and determines when the subject has provided a deep lung breath sample. If a proper sample is provided, the instrument automatically collects a breath sample and presents it to the fuel cell sensor for analysis.

The electro-chemical (fuel cell) is a porous disk with a thin layer of platinum black on both faces and saturated with electrolyte. When the subject's breath sample is drawn across the top surface of the cell, the alcohol that comes in contact with the cell's surface is broken down chemically. The alcohol is converted to acetic acid plus electrons. The number of electrons generated are in proportion to the amount of alcohol in the sample. By measuring the number of electrons (the resulting electrical signal) the output is converted to a digital BrAC (Breath Alcohol Concentration) value.

Product Specs

Sampling Requirements

Sample Error Detection
The software monitored self-diagnostic system requires proper battery power, proper instrument temperature, successful instrument pretest blank and the delivery of a "deep lung" breath specimen before automatically taking a sample. 
The disposable one-way mouthpiece is individually wrapped and can be automatically ejected from the instrument to avoid personal contact.


Power Supply
9 volt heavy duty alkaline battery for the ASIV
12 volt DC rechargeable battery for the printer with 120 or 240 volt AC automatic dual rate
12 volt battery charger
12 volt DC car cigarette lighter power adapter (optional)

Battery Capacity
300+ tests per battery on ASIV
75 tests on fully charged printer battery on RBT IV


12" X 9" X 3 1/2, 12 lbs 
Case Construction
There are ABS plastic cases on the ASIV and RBT IV printer. The carrying case is a water tight Pelicase ® .


Data Storage
The RBT IV has a 900 test memory and is also capable of reprinting the last completed test result. 
There is a four digit alpha-numeric LED display on the ASIV, and a two line 16 character alpha-numeric backlit LCD on the RBT IV printer.

The RBT IV can be connected to a computer through an RS232 adapter for downloading stored information. (RS232 jack and software are optional)

There are several test protocols available. The unit can also be manufactured to print in a number of foreign languages.
The RBT IV consists of an Alco-Sensor IV and a programmed microprocessor printer which stores test information and produces an automatic, hard copy of the test results. 
The standard RBT IV will produce an automatic hard copy documenting time, date, equipment serial number, subject identification number and test results. The RBT IV is equipped with extra memory which allows it to automatically store the last 900 tests.


The fuel cell sensor generates a response that is proportional to Breath Alcohol Concentration. The response is linear and requires one point calibration. 
Accuracy & Precision
US DOT approved for evidential use. Meets and exceeds the federal model specification for traffic enforcement and Omnibus Breath Alcohol Testing.

The fuel cell sensor is sensitive to alcohol. It does not respond to acetone or other substances which are found in the breath.

Measurement Limits
The Alco-Sensor IV can accurately detect breath alcohol levels up to .400 BrAC.

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

Sampling Rate
The patented analytical system permits quick results, more positive tests per time period with no appreciable loss of sensitivity.

Checks and calibrations should be performed with either a National Highway Traffic Safety Administration (NHTSA) approved wet bath simulator or a dry gas standard.

Any ambient temperature is acceptable provided the instrument temperature range is 10º - 40ºC.
