Polygraph Testing Machine

A polygraph testing machine, also known as a lie detector, is a device used to measure and record physiological indicators such as heart rate, blood pressure, respiration, and skin conductivity while a person is asked a series of questions. The machine works on the assumption that lying produces physiological responses that can be detected and measured. Polygraph testing is commonly used in various fields such as law enforcement, pre-employment screening, and during investigations to determine the veracity of statements made by individuals. While polygraph results are not admissible as evidence in all courts, they can provide valuable insights and help investigators make informed decisions.
