QUALITONE ACOUSTIC APPRAISER AUDIOMETER.

Purchased this of local auction . According to sellers description it was working last time it was calibrated 11-11-2014

Because I am not sure how to test it properly I am selling this AS IS FOR PARTS OR REPAIR.

Union comes in original case with two headphones , two model 621 HI-Z Dynamic cardiod electro voice made in Germany microphones , one Qualitone audio tape .

Very good cosmetic condition with very minimal signs of use …
