Measurement microphone versions designed for accurate and reliable measurements, ranging from acoustic and environmental testing to engineering and research and development applications.
Our microphones are calibrated and traceable to national and international standards, ensuring consistent and precise results.
Whether you’re looking to measure sound pressure level, frequency response, acoustic intensity, or other parameters, our wide range of microphones and accessories offer solutions to various measurement needs.
The calibrated MI19 microphone is suitable for all measurements in technical acoustics, such as machine noise, sound measurement on test benches, use in impedance tubes, sound testing and acoustic cameras.
The IEPE microphones MI15, MI17, MI19, RG-50 and MI21 are types of free-field microphones with integrated electronics that are often used in scientific research.
To ensure accuracy, these microphones can be supplied with tight tolerances of ±0.5 dB and have transmission factors from 14 mV/Pa to 100 mV/Pa.
A constant current source IEPE is used as standard, which is usually set to 4 mA.
Coaxial cables are used as feed lines and the standard microphone configuration includes BNC connectors, which are also optionally available as TNC variants.
It can be used in combination with any device that has an IEPE supply.
The measurement microphone has a Class 1 frequency response in accordance with IEC 61672.
