Polygraph - Stoelting CPS Pro - precise physiological measurement, intuitive interface

The CPS Pro is an advanced, yet very easy-to-use polygraph. It provides convenience for the operator by offering easy to interpret polygrams. The intuitive interface gives access to a question database editor, the list of persons examined and a clear report creator. The device guarantees maximum efficiency.

Reliable truthfulness testing algorithm

The CPS Pro polygraph from the world's largest manufacturer of such devices - Stoelting - bases its operation on an algorithm developed at the University of Utah. It is an integral part of the model's software and ensures maximum accuracy of truthfulness assessment. Effectiveness has even surpassed that of independent polygraph experts in all published scientific studies.

Assessment by the system is instantaneous. The operator can perform the entire process with a single click of the computer mouse.

Measurement of multiple physiological parameters

The Stoelting CPS Pro polygraph measures various physiological parameters such as blood pressure, respiration, skin conductivity and motor activity. This allows a maximally precise analysis of the subject's response to questions. The equipment is equipped with, among other things, blood pressure measuring sleeves, pneumographs, finger pads and gel electrodes.

This makes the measurement results indisputable and 100 percent effective.

Question editor and survey database

The operator can build a question database in the system and edit it at any time. They are automatically labelled and their order can be arranged with the mouse. One click is all it takes to add or remove further questions.

Additionally, the operator has access to an extensive list of the persons being examined. This contains all personal information entered before or during the check. Thus, the operator can return to previously conducted interviews at any time. In addition, each record is assigned to a specific person, making easy to organise.

Clear reports and graphs

The Stoelting CPS Pro polygraph offers recording of inspections in the form of bar charts or numerical graphs. In the case of the former, the user has a clear overview of the strength of the physiological responses to each type of question. The report is clear and leaves no doubt as to the assessment of the person being tested. The numerical analysis is equally easy to read, but has the character of a continuous graph.

The CPS Pro Polygraph offers the ability to automatically generate reports, complete with precise data of the person being tested. The report can be fully personalised and contain only selected information.

Recording ordering functions

Chart Recorder is responsible for recording clear signals that are clean and easy to interpret. In addition, the automatic measurement window function prevents the next question from being asked until the recording of the previous one has been completed. This facilitates clear recording and prevents confusion when assigning the subject's response to a particular question.

The user also has the option of setting a voice marking on the recording of the beginning of the question and the end of the answer.

Data import and export

Stoelting CPS Pro allows import of results from other polygraphs and export to other devices. In addition, if the printer settings allow, it is possible to print the test record in real time.
