When Chicago Laboratory Supply and Scale Company was founded in 1886, few could have predicted that nearly 120 years and one name change later, it would still be supplying the world’s scientists with the highest-quality instruments available.

But that is exactly the case.
Today, Stoelting Co. is comprised of four separate Divisions. Although Stoelting is a diversified company, the major product lines are all related to physiological, psychological, and psychophysiological measurement.  
This inter-relationship results in exceptional synergism and cross-fertilization of ideas.  Breakthroughs in one of our Divisions routinely find application in another Division. This kind of dynamic environment has been present at Stoelting from the beginning.

As a pioneer in the Physiological and Psychological apparatus fields, Christian Hans Stoelting built his company into one of the most successful and revered companies in the fledgling scientific world.

Tradition of innovation

In fact, from 1903 to 1943, Stoelting was nearly unchallenged as the principal provider of the material culture of American psychology. And at the St. Louis Universal Exposition of 1904, C.H. Stoelting Co. was awarded Medals for Anthropometric Apparatus and Psychometric Apparatus, awards that hang on our walls to this day.

From those humble beginnings on Chicago's west side, to our present-day headquarters in Wood Dale, Illinois, Stoelting has maintained a tradition of manufacturing and supplying superior instruments in worldwide service to science.

Of course, Stoelting's Polygraph Division has been a pioneer in the field. Nearly every advancement in the field of polygraph has come forth from Stoelting.

Stoelting created their first Cardio-Pneumo Polygraph in 1935, and has since been on the cutting edge of polygraph technology. Stoelting has constantly provided only the highest caliber polygraph instruments. 

Significant improvement

The middle part of the twentieth century brought about many advancements for the Stoelting polygraph. Many prominent polygraph examiners/schools have chosen to have their own line of polygraphs made by Stoelting. In 1951 the Reid polygraph was introduced. This 5 channel model was capable of recording signals from arm movements, respiration, GSR, blood pressure, and thigh movements. In 1958 the Stoelting Deceptograph was standardized by the US military. In 1966 Stoelting created the polygraph with a non-battery powered galvanometer.

Stoelting released the worlds first all electronic polygraph in 1974. The Stoelting Polyscribe. In 1978 the Stoelting Ultrascribe was released. This instrument took the polygraph world by storm with its modular design, allowing for three to five user-selected channels. This gave the examiner more freedom than ever, and he/she could choose how many channels he/she wanted, and upgrades were inexpensive and painless. Then in 1982 the Executive Ultrascribe hit the market. This smaller, lighter polygraph was a significant improvement in the form factor of polygraph, and became the official polygraph of the US army. The final incarnation of the Ultrascribe was released in 1983, Ultrascribe II. This instrument provided yet another revolution to the polygraph world. The Ultrascribe II featured microprocessor-controlled re-centering.

Stoelting continued the evolution of polygraph. With the arrival of the Computer Aided Polygraph System in 1988 and the Computerized Polygraph System in 1992 the polygraph entered the digital age. This brought about unprecedented accuracy, as well as, flexibility.

Our goal

Today, the CPSpro is the gold standard of computerized polygraph. Its cutting edge scoring algorithms, user friendly features, and outstanding accuracy make it the most outstanding polygraph on the market.

With such a rich history of quality and innovation, one can only ask….
