This is an inquiry message about hand held meter in the 108th China Canton Fair. (这是一条买家关于"hand held meter"的询盘信息，来自第108届中国广交会。)Inquiry Message (询盘信息) 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.
