BV-620V TFT Doppler FHR Detector

Features:

• 620 V 620VP TFT LCD displays the wave of the instant blood flow average velocity and strength. It  prints the monitoring blood flow curve simultaneously;
• Detect the blood stream status of arterial/venous by 8MHz probe;
• Detect the blood flow average velocity, detect the result of fingers/toes and part of body's vein anatomies operation;
• BV-620V 620VP(TFT) portable bidirectional vascular Doppler with large color LCD screen;
• Built-in ARM microprocessor & real-time displays blood flow velocity waveform;
• Can store 50 detected waveforms;
• High-speed USB/RS -232 port, can be connected directly to computer to analyze, store, and print the waveform data;

Attention: 

          BV-620V without thermal printer.

          BV-620VP with thermal printer and can record the waveform of blood stream when it is connected with the power supply.
