Advantages of
THE POLYGRAPH
It is an effective investigation tool that is between 90% and 95% accurate. This will save
unnecessary waist / loss of valuable man hours during a serious investigation.
It is a very effective interrogation tool.

1) Respiration,
2) Electro dermal activity,
3) Cardio changes,
4) Relative changes in the total blood volume
using the (Photo Plethysmograph) and
5) Movement to detect certain physical
