Review on 🔊 Accurate Professional Sound Level Calibrator Decibel Meter with 94dB, 104dB, and 114dB Calibration Levels by Payton Stovall

This device did what it was advertised for. It has a threaded tripod mount which is essential and I used it for a few days but on day 4 I found that the USB cable port on the unit was faulty. The tripod may have fallen on the grass in my absence but I was a bit disappointed with how easily it broke and the data I had recorded for the day was unavailable. I was also a bit confused as to whether it runs on the external battery I plugged in or the ones I plugged into the device. Other than that, the software was pretty easy to use and I would advise anyone buying this device to be very careful with it. I found a CDC recommended IOS app (NIOSH) there, so I'm trying that instead. However, I'm not sure if the iOS app can record whole days of data like this device.
