Polygraph

Polygraph equipment is a type of technology used to measure and analyze physiological responses from a person. This type of equipment is used to detect deception and verify truthfulness in a variety of situations such as criminal investigations, employment screening, and even lie detection. The equipment typically consists of a computer, sensors, and a polygraph machine. The sensors measure changes in the person's physiological responses such as pulse rate, respiration, and sweat gland activity. The computer then analyzes the data and produces a report.

The price range of polygraph equipment varies depending on the manufacturer and the specific features of the equipment. Generally, the cost of a basic polygraph machine ranges from $1,500 to $3,000. High-end models can cost up to $20,000. Some of the leading manufacturers of polygraph equipment include Lafayette Instrument Company, Axciton Systems, and Limestone Technologies. These companies provide a wide range of products to meet the needs of various customers.
