I'm reaching out because I'm in need of a replacement transducer probe for my portable ultrasound machine, which has unexpectedly stopped functioning. It's crucial for my work, so I'm looking for a reliable replacement as soon as possible. If you have compatible probes available, please let me know about the options, including pricing and lead times. Additionally, I'd appreciate any technical specifications or compatibility details that could help ensure I get the right probe for my device. If you could also provide information on warranties or return policies, that would be great. Looking forward to your prompt response so I can resolve this issue quickly. Thank you!
