About Intoximeters®

Industry leaders since 1945.

 

Intoximeters, Inc. is a privately held company headquartered in St. Louis, Missouri USA with a subsidiary office in Totnes, Devon UK. Intoximeters produces and markets a full line of alcohol breath testing instruments. Our team’s expertise and experience is second to none.

Since 1945, Intoximeters has been a leader in the breath alcohol detection field. Early on, law enforcement, probations and correction agencies were the primary customers for this type of equipment. However, as the extent of alcohol abuse in society became more recognized, other markets for breath alcohol testing products developed – most notably in the industrial occupational health sector.

Although initially driven by federal mandates, the costs associated with alcohol abuse in the workplace have encouraged more and more employers to institute alcohol and drug testing on their own to reduce absenteeism, workers compensation costs, accident insurance costs and to improve overall safety in the workplace. Intoximeters’ products, designed for use in law enforcement environments, have been easily adapted for a wide range of industrial applications.

Intoximeters has fully utilized advances in both sensor and data processing technologies. Today, there are a wide variety of mandated testing protocols at the local, state and federal levels, many with strict reporting requirements. Intoximeters has responded to this market need by developing a complete line of instruments with advanced data processing and communications capabilities.

Intoximeters, Inc. also provides comprehensive customer support by offering training courses in the operation and maintenance of each of its instruments and associated software products.

A Brief History of Intoximeters

1937

The company founder, Dr. Glenn C. Forrester, discovered and patented a process for capturing alcohol from a breath sample. The result was the development of a portable, roadside instrument used to collect evidence in suspected drunk driving cases. Breath sampling was an innovative technique for blood alcohol determination at that time.

1937-1941

Dr. Forrester devoted most of his energy to research and pilot studies to establish the validity of breath alcohol analysis, until World War II interrupted his efforts.

1945

Intoximeters was incorporated by Dr. Forrester.

1946

Dr. Forrester. applied for a patent, “Method for Determining Breath Alcohol Content” (patent granted in 1952). The State of Michigan initiated a statewide breath testing program using the Portable Intoximeter. Dr. Forrester’s success in these early efforts eventually gained wide support in the forensic community for breath alcohol analysis.
In the winter of 1946-47

Dr. Forrester participated in introducing chemical tests in the State of Michigan, as a law enforcement aid to curb drunk driving. The program was directed by Dr. LeMoyne Snyder, Medicolegal Director of the Michigan State Police. Dr. C.W. Muehlberger, Toxicologist of the Crime Detection Lab of the Michigan Department of Health, contributed generously his scientific expertise and experience with chemical tests for alcohol. The Attorney General’s office advised on legal matters, and Captain C.J. Scavarda, in charge of Traffic and Safety, was invaluable in translating the program into a practicable standard procedure.


Mid to Late 1950’s

The Photo-Electric Intoximeter (registered originally by Dr. Forrester) used deep lung breath of a fixed volume and pre-packaged chemicals in conjunction with photo-electric measurements to determine blood alcohol concentration.


In the 1970’s

Intoximeters brought to market a flame ionization Gas Chromatograph (GCI MKII and MKIV). These instruments could directly sample a subject’s breath or they could analyze a breath sample collected at another location using the Indium Encapsulation System. These indium tubes captured three separate samples of a breath specimen. The collected samples would be preserved until they could be presented to the GC for analysis.


Mid 1970’s

Intoximeters introduces the first of the Alco-Sensor line of handheld breath alcohol analyzers. This line of handheld fuel cell instruments is the most prolific line of evidential grade alcohol breath test instruments made to date.


Late 1970’s

Intoximeters introduces the first evidential fuel cell based instrument. The “Auto Intoximeter” (Auto I)


1980’s

Intoximeters offers the Intoximeters IR 3000 infrared based evidential system. This analyzer lead breath testing into the computer age. The IR 3000 was the first to integrate a computer with a breath test instrument. The system allowed the operator to collect data about the subject and the arrest and attach it to a test result.

1981 – IR 3000 is offered with a dual sensor system including a tin oxide sensor. This device was used to identify compounds that could be found in the human breath and might interfere with the infrared analysis.

1983 – IR 3000 is offered with a fuel cell as a second sensor. This device is the first dual analytical fuel cell infrared analyzer commercially available for evidential breath testing.

1983 – The IR 3000 used in Alaska is offered as an evidential breath test system that utilizes a dry gas standard for performing periodic accuracy checks


1990 

Intoximeters implements a patented analysis technique in the Alco-Sensor IV where the fuel cell signal is integrated, and this integration is used in the determination of the alcohol concentration. This technique proves to be a benchmark improvement in fuel cell analysis in that it overcomes the “slumping” effect that is evident in systems that use a pure “peak” or rate of reaction analysis. This patent allows the Intoximeters’ fuel cell instruments which employ this technique to offer accuracy and repeatability on par with the desktop evidential systems.


1993

Intoximeters introduces the Intox EC/IR. This instrument sets the standard for bench top, fuel cell based evidential systems. With its use in several US states as the primary evidential testing system and its approval and use in the UK for drink drive enforcement, the EC/IR offers features and an ease of maintenance that make it an attractive alternative to infrared based analyzers.


1994-95

The US Department of Transportation mandates workplace alcohol testing for safety sensitive positions that fall under the DOT jurisdiction. This group includes truck drivers, pilots, train conductors and ship captains, to name a few. To meet the needs of this market, a suite of products (using existing or new platforms) was introduced:

  • Alco-Sensor IV /RBTIV
  • Alco-Sensor IV with memory and serial printer
  • Alco-Sensor IV with Alco Sensor IV Utility
  • Alcomonitor CC
  • Intox EC/IR

1997

Intoximeters places more than 300 Intox EC/IR instruments in UK police constabularies. To support a growing sales demand in Europe, an office in the UK is opened to offer both marketing and after sales support for Intoximeters products.


2000

Intoximeters introduces its first @Point of Arrest system:
Point of Arrest testing is a response to the “rising blood alcohol” contention which is a common defense used to challenge breath test results in court. Roadside evidential testing systems, such as the Alco-Sensor IV XL @Point of Arrest system, are one solution to eliminate this concern.


2004

Intoximeters introduces the Intox EC/IR II and Alco-Sensor FST:
The EC/IR II, the replacement for the benchtop EC/IR in the Intoximeters product line is introduced to the market and selected for use in statewide programs in West Virginia and Tennessee.The Alco-Sensor FST is the latest instrument in the Alco-Sensor Product Line that offers automated sampling at a low cost. The Alco-Sensor FST offers integral design features that are aimed at enhancing operator safety during its use.


2009
The Intox EC/IR II was approved for evidentiary use by the Canadian Society of Forensic Science in Canada, along with the Alco-Sensor FST, approved for use as a screening device. Previously approved devices in Canada include the Alco-Sensor IV (Screening device, 1996).

2010

Intoximeters introduces the Alco-Sensor V line.

The Alco-Sensor V line of products offers a range of configurations; from a standalone handheld instrument (ASV), to a handheld instrument with print capabilities (ASV and printer) to full systems (RBTV and Alco-Sensor V @Point of Arrest system) with data input and print capabilities.


2012

Intoximeters introduces the Intox EC/IR II.t transportable breath alcohol testing device.

Intoximeters achieves ISO 17025:2005 Calibration Laboratory Accreditation from the American Association for Laboratory Accreditation (A2LA) in the field of calibration services for breath alcohol instruments.


2013

Datamaster DMT Acquisition – Intoximeters acquires National Patent Analytical Systems’ breath alcohol testing business.


Macquorn Rankine Forrester, Sr.

 

May 5, 1933 – April 20, 2016

 

Mac Forrester

April, 2016 –

The Intoximeters family and the Breath Alcohol Testing industry lost one of its pioneers.

In memory of Macquorn “Mac” Forrester:

The first breath alcohol testing instrument (The Drunkometer) was developed by Dr. Rolla N. Harger in 1938. In 1941, the Intoximeter was invented by Dr. Glenn C. Forrester. This device was closely followed by the Alcometer, which was invented by Professor Leon Greenberg. All of the breath collection devices were designed to measure breath alcohol concentrations that were related back to blood alcohol concentrations.

In 1954, Robert Borkenstein, an officer with the Indiana State Police, invented the Breathalyzer.

Breathalyzer breath testing instruments were originally manufactured and sold by the Stevenson Chemical Corporation of Red Bank, New Jersey. The rights to such instruments were subsequently acquired by the Smith and Wesson Electronics Company of Springfield, Massachusetts, which manufactured and through its mature law enforcement distribution channel successfully sold the Breathalyzer until 1984.  Due to this success,“Breathalyzer” earned the most recognized name in the industry.

In 1959, Mac Forrester took the helm at Intoximeters, Inc. from his father (Dr. Glenn Forrester).  Breath alcohol testing instrumentation was a fledgling industry and Intoximeters competed directly with its Photo Electronic Intoximeters (PEI) against the industry leading Breathalyzer. 

Unlike his father, who was more of a scientist than businessman, Mac was prepared to use both his science background and his Harvard business school training to build a business that would lead the breath test instrument industry for the next six decades.

Mac drove innovation in the industry.  He was responsible for developing:

  • The first Gas Chromatograph breath alcohol analyzer (GCI),
  • The first evidential fuel cell based instrument; the Auto-Intoximeter (Auto I), 
  • The first infrared based breath alcohol instrument with an integrated computer for data entry (Intoximeter IR3000), 
  • The first instrument with fuel cell and infrared based analytical technologies combined (IR3000DFC), 
  • The premier line of handheld instruments, The Alco-Sensor line, which with the help of Tom Jones from Lion Labs and the engineering expertise of Karl Wolf Sr., was instrumental in defining the fuel cell based Preliminary Breath Test market, and
  • The market for dry gas calibration systems.

At the time of his death (April, 2016), Intoximeters, Inc. is recognized as not only the oldest but the most successful breath alcohol detection instrument manufacturer and marketer in North America; if not the world. This success is largely due to Mac’s leadership, vision and relentless work ethic.

Mac in his early years was known for his larger than life personality, his desire to impose his will on the industry and commitment to the success of his company.  Sometimes this gregariousness got Mac into trouble, but mostly it worked to his advantage.  In all cases, everyone in the industry knew Mac was a force to be reckoned with.    

In the later years Mac was less aggressive.  Mac was able to manage Intoximeters such that it earned and maintains a reputation for providing a highest level of customer service, it has the premier sales force in the industry, it has a commitment to excellence and is the leader in innovation in the industry.

Mac’s legacy will be his company, the imprint he made on all of the employees that worked with him, and all of the relationships he built through the business, his personal friends and his family. 

He will be sorely missed.
