These premium quality Polyvinylidene Fluoride (PvDF) membrane hydrophones represent the gold standard for both accuracy and stability. Because of their performance characteristics and long-term reliability, Acertara’s hydrophones are used daily in research and development, regulatory, and quality control laboratories worldwide. All Acertara hydrophones are provided with a calibration that is traceable to the National Physical Laboratories in England. Hydrophone models are available with responses that are flat and stable from 1-40MHz.
Fig. 1 (above left): Our typical model 804 response is flat and linear from 1-20MHz and beyond.
Fig. 2 (above right): Our typical model 805 response has less than a 3dB variance over its usable range from 0.25MHz to well beyond 50MHz. Standard calibration data is provided from 1-40MHz
The design and construction of Acertara’s bilaminar PvDF membrane hydrophones were developed based on the collective experience gained from hundreds of testing projects as well as 750 notified body submissions. Our hydrophones produce highly accurate and consistent data resulting in reduced testing times and, ultimately, lower testing costs
