Why people pick it

Certified to IEC 61672-1 Class 2, so readings are consistent with the standard used for occupational noise checks, per the maker's spec page

Backlit display with 0.1 dB resolution, plus Data hold and Max hold for reading spot checks
Runs about 50 hours on one 9 V battery and mounts on a tripod for longer monitoring

Know before you buy

No data logging or PC connection; readings must be written down as you take them
No time history, Leq averaging or frequency spectrum, only A and C weighted levels
