Inquiry (采购产品): hand held meter Hello, I need a hand held meter to detect ultrasonic waves. I think the waves are being made by a ultrasonic generator. Do you have a meter here? Or do you know where I can find one? I do not know much about ultrasonics and need help with this. I believe that someone is shooting this through my home. I have a 2 yr old son and I'm worried of what the long term affects this will be on him. So, any help would be greatly appreciated. Thank you.
