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 reaching out to inquire about your pregnancy ultrasound equipment options. We are particularly interested in understanding the features, specifications, and pricing of your available models. Additionally, it would be helpful to know about any warranties or service programs you offer. Could you also provide information on lead times for delivery and any bulk purchase discounts? We're looking to make an informed decision soon, so timely feedback would be appreciated. Thanks for your assistance!
