The small sensing area is coated with thin layers of metal and/or polymers that can be damaged, leading to degradation in performance. Dropping or bumping the tip of a needle hydrophone on a hard surface will generally result in some damage to the device. Even using a soft brush to remove bubbles may be risky as a slight misplacement can bring the hard part of the brush against the hydrophone. Instead, we recommend using jet of water from a squeeze bulb or a syringe, or a low pressure stream of clean air or other gas to remove liquids or particles.
