MKS 231 1/2“ Microphone Capsule for random incidence sound field • WS2D acc. IEC 61094-4 • random incidence • 3,5 Hz to 16 kHz • 15 dBA to 149 dB • 200 V polarization The 1/2“ microphone capsule MKS 231 has a random incidence response and is therefore optimized for correct measurements in diffuse and reverberant sound fields or in acoustic couplers. The equalization of the static air pressure is by means of a capillary to the preamplifier (rearvented). The microphone capsule is suitable for sound level meters of Type 1 acc. IEC 61672. Delivery Microphone capsule, stainless steel in wooden case 90 mm x 90 mm x 40 mm Options and Accessories Protection grid for rugged environment instead of standard protection grid Electrostatic actuator instead of standard protection grid Adapter for 1/2“microphone capsules to 1/4“preamplifiers Angle adapter 1/2“ Dehumidifier adapter 1/2“ Wind
