南非采购需求：黑白超声波、彩色多普勒超声波、心电图、数字X光、病人监护仪

I'm looking to purchase a basic ultrasound system specifically designed for small animals, complete with a suitable probe. It's important that the ultrasound machine is user-friendly and provides accurate imaging for diagnostic purposes. Could you please provide more details about your available models? I'd like to know about their specifications, pricing, and any additional features that may benefit small animal practices. Understanding the warranty and support options would also be helpful. Looking forward to your prompt response!
