Decent Cheap Sound Level Meter on eBay
So, while I have been looking for power sensors, I also came across a decent little Sound Pressure Meter. At this price of $29, new, shipping included, I bought this as a spare for general lab sniffing and as a backup to my monster BK meter. (I think this whole meter is lighter than the BK’s battery!) eBay Item # 200518775563 (I found a really cheap analog meter, $20 with shipping, at Item # 250627590679, but why pay that when $9 more gets you a lot more, especially Peak Hold.) As usual, I have no connection to this seller, other than I just can’t pass up buying meters!
