ATech Investigation Services provides certified polygraph examinations for individuals, attorneys, and corporations throughout New England. Whether you are dealing with infidelity, employee theft, or a legal matter — a professional polygraph can provide the clarity and evidence you need.

What Is a Polygraph Examination?

A polygraph — commonly known as a lie detector test — is an instrument that measures and records several physiological indicators such as blood pressure, respiration, and skin conductivity while a subject is asked a series of questions. When administered by a certified examiner, the polygraph is a highly effective tool for detecting deception and confirming truthfulness.
