The Chison ECO3 black and white portable ultrasound machine is one of the few non-color systems to have Pulsed Wave Doppler. This makes it unique in its category and price range.

Advanced imaging technologies, including compound imaging, speckle reduction, and harmonics give the Chison ECO3 an edge in the portable black-and-white ultrasounds at a very inexpensive price.

A 12-inch LED monitor also provides a crisp image with a very wide viewing angle, which is rare in this category (most use a less-expensive LCD screen with a limited viewing angle). Additionally, the LED screen can be tilted at up to a 30-degree angle.

The ECO 3 has measurement packages for OB/GYN, urology, abdomen, basic cardiac, vascular, small parts, and pediatrics. For urology, the ECO3 features a rectal linear probe, allowing for better viewing of the prostate. Dual probe ports allow for easy transducer switching.
