The WEK-1438 Doppler String Phantom,WEK-1438 Doppler Phantom is an essential tool for Doppler Ultrasound. Its crystal controlled motor accurately generates 16 preprogrammed waveforms using advanced string target technology. Since speed is adjusted 1,000 times per second, you can be confident in its precision and repeatability.



WEK-1438 Doppler String Phantom,WEK-1438 Doppler Phantom can be set for use with water or velocity-corrected fluid. When using water, it adjusts the
string speed accordingly so varying speeds of sound in water won’t affect your tests. Unlike fluid-flow phantoms,
the target never changes; you know what your test results should be every time.

WEK-1438 Doppler String Phantom,WEK-1438 Doppler Phantom includes a user’s manual and a rugged carrying case. Additional options include custom programming of special waveforms.
