There are a few polygraph instrument providers in the market and most of them are american made. B.E.A.R. FORENSICS uses a variety of polygraph instruments from different manufacturers to ensure that we are technically savy to addres our client's needs. All instruments have proven to be reliable and B.E.A.R. FORENSICS has been able to depend on professional service after the sale as well as a reliable instrument.

Although each Polygraph Examiner maintains their own instrument, it is the policy of B.E.A.R. FORENSICS that its Polygraph Examiners remain versitile and flexible and must be fluent with every instrument in our inventory.

B.E.A.R. FORENSICS primarily utilizes digital polygraph instruments for our Polygraph Exams, also referred to as CPS (Computer Polygraph System). We can however, utilize any instrument young or old that has been produced within te last 30 years.

A modern polygraph instrument typically consists of :

  • Data Acquisition System (DAS) which is the system that acquires the data from the accessories and translates it into digital format, so it can be read and interpreted by a computer and Polygraph Examiner
  • Pneumographs which record respiratory activity
  • Blood Pressure Cuff which records cardiovascular activity
  • Galvanometers which record sweat gland activity
  • Other accessories can be used to improve readings like for example : - Electric Activity Sensor

Below, we have included, as an example, images of the prefered CPS (Computer Polygraph System) at B.E.A.R. FORENSICS, the Limestone Technologies DATAPAC_USB.

Limestone Technologies Inc. offers a leading-edge data acquisition system. The DataPac_USB™ uses 16-bit Sigma Delta technology to acquire precision accuracy for the measurement of human physiological signals.
