The Stoelting polygraph typically consists of several key components: the polygraph itself, which records physiological responses; sensors, including pneumographs to measure respiratory effort, galvanic skin response sensors to assess sweat gland activity, and blood pressure cuffs to monitor cardiovascular responses; and a computer interface for data analysis. The system also includes a printer for outputting results and a control unit for managing the equipment. Unfortunately, I can't provide images, but you can find visual representations on the Stoelting website or through relevant scientific resources.
