Bestman Vascular Doppler BV-620V

Specifications

Vascular doppler detects the blood stream status of arterial/venous by 8.0 MHz, detect the blood flow average velocity, 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 spectum line;
LCD can display the instant blood flow average, wave form intensity and the detecting result of the blood stream;
RS-232 port can connect the unit with a computer and store the data.
