Features:
Detect the blood stream status of arterial/venous by 8.0 MHz, detect the blood flow average velocity, and detect the result of finger/toes and part of body's vein anatomies operation;

Display the waveform and the detecting result of the blood stream average velocity and the spectrum line;

LCD can display the instant blood flow average, wave form intensity and the detecting result of the blood stream synchronously;

Built-in printer with high precision can print monitoring blood stream graphics synchronously;

RS-232 port can connect the unit with a computer and store the data.
