What is a polygraph?
A polygraph, commonly known as a lie detector, works by measuring physiological responses—such as heart rate, blood pressure, respiratory rate, and skin conductivity—while a subject responds to a series of questions. These responses can help determine whether the person is being truthful or deceptive, as certain physiological changes often occur when someone is lying.
​
At Precision Polygraph, cutting-edge technology is used to ensure the highest quality standards in polygraph testing. With state-of-the-art Lafayette computerized instrumentation, they employ the most advanced systems for monitoring and analyzing the physiological data. This equipment, paired with sophisticated techniques, allows for a precise assessment during polygraph exams.
