BENTHOWAVE INSTRUMENT INC. Acoustic Transducer & System
BII's high temperature hydrophones are developed for uses in high temperature materials (gases, liquids or solids) up to 120°C (248°F) and 198°C (390°F). The differential output and high capacitance of the hydrophone can be customized to drive long cable and reduce the pickup of EMI noise. Solvents should not be used with hydrophones, such as hydrochloric acid, isopropyl alcohol, ethyl lactate, acetone, xylene, Iso hexanes, mineral spirits, etc... The hydrophone should not be used with flammables, explosives and corrosives.
