The Models 512 handheld pulse oximeters incorporate “digital” signal processing. This advanced technology is able to process pulsatile signals at much higher resolutions and speeds of 100 times per second. This processing technique results in improved pulse oximeter performance during motion or low perfusion, where traditional handheld monitors fail. Manufactured 2000, 2002 and 2003.
