S218 is a full-digital black and white ultrasonic diagnostic instrument with high cost performance and high stability. This model supports convex array, cavity, high-frequency linear array, micro-convex, rectal and other probes, and is rich in obstetric and conventional measurement software. The model features a more stable LED display based on the original SM218, adding 16 pseudo-color display modes and support video printers and external VGA displays and USB ports.
