Get Honest Answers with Our Professional Polygraph Exam

When the truth is unclear, a polygraph examination in Sacramento can help you find answers. If you are dealing with a legal issue, responding to an accusation, or trying to resolve a personal concern, getting reliable answers is important. 

At Bonnington PI, we arrange professional lie detector tests through an independent, licensed polygraph examiner. 

Our Sacramento private investigators handle the test discreetly and professionally, giving clients across Sacramento and Northern California clear answers they can rely on.

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.

Polygraph examinations in California are conducted privately to see how honestly a person answers specific questions.
