Common name: Microtech Gefell MK 250
Production Status: In production
The MK 250 is a 1/2” microphone capsule with a free-field response and is therefore optimised for correct acoustic measurements under free-field conditions with 0 degree incidence. The equalisation of the static air pressure is achieved via a tube between the inside and outside of the capsule connected to the preamplifier (rear-vented). The microphone capsule is suitable for sound level meters of Type 1 acc. IEC 61672. Includes wooden box.
