Since 1886, Stoelting has furnished physiological measurement instruments
and psychological test materials for over a century. Stoelting
invented the first modern polygraph in 1930, and virtually
every advance in polygraph instruments since then has been
by Stoelting. Electronic Recording Channels were introduced
by Stoelting in 1946; Multifunction Recording Channels in
1966; CAM in 1968; modular design in 1977; CLC push-button
re-centering in 1980; Computerized Assisted Polygraph in 1988;
and the Computerized Polygraph System in 1992.
A worldwide influence
Stoelting's Computerized Polygraph System contains the only
scoring algorithm based on verified data from major government
law enforcement agency cases and independently validated by
research supported by the National Institute of Justice.
