We are selling this vintage Bruel & Kjaer type 2232 Precision Sound Level Meter. We did test it with batteries and it does power on (you can see pictures with different measurements on it), but it is due for calibration according to the label on it. It requires two 9V batteries, which will NOT be included. It also comes with a case as you can see in the pictures. Please see the pictures for more details. Thank you!

Measurements:

Roughly ~10.5" in length
