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 am interested in acquiring a standard sonar machine designed specifically for sheep monitoring and management. This technology is essential for enhancing our livestock operations, allowing us to track the location and health of the animals more effectively. I would like to know more about the available models, their specifications, and any unique features they offer that set them apart in the market. Additionally, it would be helpful to receive details about pricing, bulk purchase discounts, and lead times for delivery. Our goal is to integrate this system into our existing infrastructure seamlessly, so information on compatibility with other technologies would be appreciated. Looking forward to your prompt response with the necessary product details, and any recommendations you might have based on your expertise.
