A polygraph (popularly referred to as a lie-detector) is an instrument that measures and records several physiological responses such as: blood pressure, pulse, respiration, breathing rhythms, body temperature and skin conductivity while the subject is asked and answers a series of questions. Polygraphs are in some countries used as an interrogation tool with criminal suspects or candidates for sensitive public or private sector employment.

Our polygraph specialist is highly qualified and amongst only a few in the country. We recommend using this service for a variety of needs such as investigations into internal theft.
