Microphone Arrays
One of the most important parts of an Acoustic Camera is the microphone array. It determines the spatial distribution of the acoustic microphones and therefore measurement performance of the whole system. In order to achieve the maximum possible performance in any given application, we offer a wide variety of microphone arrays. No matter if the measurement is beamforming, intensity or holography ... we have the right microphone array. For special applications we can design and build custom made microphone arrays according to the requirements of the application.

Primary Calibrators
Why is the adjustment and primary calibration of air sampling instruments necessary? Instruments that sample air must be flow adjusted, calibrated and routinely checked to ensure the accuracy of flow rate. The frequency of flow adjustment and/or calibration depends on the use, care and handling of the air sampling instruments and the regulations they are complying with. Determining exposure to various physical, chemical, radiological and biological substances is based on the accuracy of the total volume of air sampled and the sample duration.
