What Is a Polygraph Test?
A polygraph test, often called a lie detector test, records physical responses when a person answers questions. During a polygraph test in Sacramento, the examiner measures physical changes in the body, like –
- Heart rate
- Blood pressure
- Breathing patterns
- Skin conductivity (sweat gland activity)
These responses help the examiner compare normal reactions with answers to important questions and detect possible deception.
At Bonnington PI, our trained and licensed polygraph examiners in Sacramento perform each test using proven methods and professional-grade equipment.
