Cleaning the instrument

Clean the instrument after each extended deployment to remove deposits that may have accumulated.

Do not use an ultrasonic bath to clean your instruments. Ultrasonic vibrations can break the wire bonding inside the transducers.
Type Procedure Notes

General/biofouling

To clean the exterior, soak in a mild detergent, then scrub the instrument with a soft brush.

Avoid scratching the plastic (scratches make future cleaning more difficult).

Calcification,
encrustation

Soak in vinegar for six hours, then scrub the surface using a soft brush.

Soaking in vinegar for more than 24 hours may damage the O-ring and increase the risk of a leak.

Cleaning the pressure sensor

Avoid touching the diaphragm when cleaning the sensor. Any deformation will permanently affect performance.

  1. Unscrew the sensor guard using a coin or a large flathead screwdriver. Do not apply excessive force, especially when using the screwdriver.

  2. Rinse the area under running water. If this fails to remove the deposits, try soaking in vinegar.

  3. If unsuccessful, contact RBR.

Cleaning the CT cell

Typically, the white ceramic tube inside the CT cell does not need cleaning because the UV radiation protects it from biofouling. If some cleaning is still required, use a very thin cloth. Feed it throw the tube and floss back and forth.

  1. Feed the cloth through the guard and remove the biofouling from all surfaces.

  2. Rinse the area under running water.

  3. If unsuccessful, contact RBR.

Cleaning the housing

Scrub the surface using a soft brush.
