A Probe Microphone is specially designed for difficult measurement situations, for example in high temperatures or airflow.
Its right-angle design makes the probe microphone particularly well suited for measurements on exhaust systems and other machinery in general, as well as for scanning surfaces such as loudspeaker cones and loudspeaker cabinets.
Its very small size, low weight and all stainless-steel construction, make the probe robust, easy to handle and simple to mount.
