Features: Detect the blood stream status of arterial/venous by 8.0mhz, detect the blood flow average velocity, detect the result of finger/toes and part of body's vein anatomies operation. Detect the blood flow average velocity, detect the result of fingers, toes and part of body's vein anatomies operation; it can be used to listen the temporo-mandibular joints (they become noisy when they start to brake because of the bite problems), assist doctor to check the conditions of the joints and predict the result of treatment. Built-in arm microprocessor & real-time displays blood flow velocity waveform; Choose menu by pressing keys, store 50 curves; High-speed usb port, can be connected directly to computer to analyze, store, and print the waveform. Delect the pulse rate and show pr simultaneously Ppg probe for option.
