The industry-leading true 8-channel system employs Limestone Technologies Inc.’s exclusive DataPac_USB™.

The DataPac_USB records blood pressure, heart rate, upper and lower respiration, temperature, skin conductance (EDA) and and two countermeasure channels (piezo and pneumatic). As many as 10 channels can be displayed simultaneously, more than any other vendor.

Polygraph Professional Suite is also unique in supporting the simultaneous display of both automatic and manual EDA channels.

Polygraph Professional Suite leads the industry in supporting the digital audio/video recording of an exam thanks to our powerful and exclusive ChartSync™ utility.

Examiners can now digitally record the exam itself, as well as pre-interview and post-interview. Alternatively, if preferred, the three elements can be recorded as a single continuum.

Whatever your choice, the digital recordings are time-aligned and completely synchronized with the chart information for playback post- exam.

Synchronizing the exam video with the subject's physiological readings enables observation of any countermeasures and/ or facial tells. Both the digital recording(s) and session information are archived together for later review and analysis. It's as easy as 1-2-3 thanks to Limestone Technologies Inc.'s exclusive digital playback controls.

If desired, the Video Window can be made transluscent to show the underlying chart as shown at left.

As an option, the subject can be viewed through the Video Window, rather than live, throughout the course of an exam.

Polygraph Professional Suite exclusively offers four convenient Caliper Measurement Controls. These make manual scoring much easier than anything offered by the competition.

Limestone Technologies Inc. provides measurement algorithms for calculating BPM/Beats per minute, line length, signal amplitude, delta time as well as beat to beat interval.

Limestone Technologies’ is the only polygraph vendor that offers CDR/DVD software controls that are completely integrated into the Polygraph Professional Suite software.  The other polygraph vendors rely on third party software solutions to complete this task and these utilities are not integrated into their polygraph software.  We support what we create

Polygraph Professional Suite™ makes report writing easy; you can automatically fill your customized report templates with all of the relevant polygraph exam information.  Examine details, date, time, fingerprints, exam type, questions used, conclusions and summary.  This software utility helps you to make your report writing efficient by providing a consistent and clear standardized report style that can be easily customized to your organization.

Polygraph Professional Suite software supports a multi language platform.  Special attention has been given to ensure that our software can be made available in several languages without requiring any additional CDs or software versions. Our clients can select their desired language at installation and the software will install appropriately.  The software is currently available in English, Spanish and French. The ability to switch between languages after Polygraph Professional Suite™ has been installed is exclusive to Limestone Technologies Inc.

Limestone Technologies provides complete access to all of the raw data collected during the polygraph examination.  This is available in a convenient comma-delimited file that can be exported to Excel, Word, SAS, etc.  Limestone Technologies Inc. is the first and only polygraph vendor with an open data format.  All of the other polygraph vendors hide their data in a proprietary format that is not revealed.  This proprietary approach makes validation of data collection impossible and impedes valuable research opportunities.  

Visual stimulus can be presented to the examinee using any second display device that accepts a composite, SVideo or SVGA connection.

Charts can be “dragged back” during recording to re-examine earlier questions and anomalies. Polygraph Professional Suite’s graph controls monitor data real time, all the time.

No other instrument can boast this type of control and convenience.

Change colors, graph plotting speed, line thickness, and scale controls for X-axis and Y-axis, all at the click of a button.

Vertically place annotations anywhere desired from the top to the bottom of a chart.

With this flexibility and control over the display of charts, an examiner can fully maintain authority over the final look of a chart.

Superior software means more options for the examiner.

Another example of this superiority is the ability given examiners to pre-define event markers by linking them to the function keys of a keyboard.

The example at left shows some of the possibilities.

It’s simple to digitally record dictations that can be assigned to any chart.

Any number of dictations can be recorded for association with an individual chart.

This utility aids the examiner in jogging the memory during later review of the charts.
