The Fully Automatic C-Mic Tester: Based on the BK3010V2 C-Mic Tester, the BK9010B is our fastest C-mic test system. Fully automatic, the BK9010B loads the mics in place and after testing, it sorts passing microphones into 8 quality classes, and failing microphones according to the reason they failed. Each mic is put into its appropriate bin. As testing progresses, you can view the data graphically in real time or save it to be viewed or analyzed later.

This machine is also avaliable as the BK9010E Fully Automatic MEMS Mic Tester. If you'd like to know more about our BK9010 fully automatic testers, email me here.
