Here you will find pre-polarized measurement microphone capsules for industrial acoustics. All measurement microphone capsules have an omnidirectional polar pattern and are available in 1/4″ and 1/2″ sizes.
The MKS222E is suitable for infrasound measurements, while the MC14A, MC14B, and MK301E models are suitable for ultrasonic measurements.
For very high noise levels above 160 dB, we offer pressure field microphone capsules with the industry standard designation WS3P, types MK341E and MK342E.
All microphone capsules are supplied with a factory calibration certificate. A corresponding calibration file is available upon request.
