Polygraph
Product Code : JA-PLE-2379
The Polygraph (SKU JA-PLE-2379) is an ink writing chart recorder that traces several physiological signals side by side on moving chart paper, for psychology and physiology laboratories. This polygraph uses modular pen motors that can be interchanged in a minute or two, 120 mm ink writing pens with a frequency response of 70 Hz at -3 dB, a quiet synchronous motor chart drive and Z-fold chart paper for easy reference back through a recording. It is supplied by JaincoLab for teaching and research laboratories.
