hospital  medical equipments vascular doppler fom Bestman BV-620VP

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.

Software is option
