REED InstrumentsR8080 Sound Level Meter, Datalogger with Bargraph, 30 to 130 dB

Battery needs replacement each day, and unit has limited data, only 24 hours.

4/13/2019. Had a significant issue with a neighbor who was creating a neighborhood disturbance to all the neighbors within 500 feet in a residential area. This tool provided metrics useful to convince local city authorities to take action and resolve the issues. Worth the cost. I did extensive research for a reliable unit that can record readings and of the two on the market under $800, this was the best. Very pleased with the performance and ease of operation. Comes with a hard case but I also bought the soft carry case and the calibrator device. Without the calibrator you have no evidence to convince authorities that the readings are reliable and they will not accept them.

Item was received in previously-used condition: scratched display screen w/ protective overlay film missing. Be sure to check your unit closely to ensure it isn't a previously-owned return. Note unique unit number on the picture of the back of the sound meter to make sure you don't receive this same unit.

Buyer Beware:The product itself seems fine but Amazon has a history of selling used units as new. If you call and complain with evidence you can get a 50% discount on the used unit.

The device accurately recorded noise levels under varying conditions to support our analysis requirements.
