The Hydro-Wiper: Clean optical sensor windows and underwater camera housings.

“The wipers have made a huge improvement in data quality and reduction in cleaning effort. The ports can now be left for several months at a time without the need for manual cleaning while the port surface remains nearly as clean as immediately after a manual cleaning by divers”. UC San Diego Scripps Plankton Camera team.

 

What is a Hydro-Wiper?

The Hydro-Wiper is an innovative mechanical wiper system designed to fit easily to a wide variety of optical instruments. Talk to us about customization to fit your needs.

Using a regular gentle brushing action, the Hydro-Wiper keeps the optical window of the instrument clean from bio-fouling and unwanted deposits such as mud.

Cost effective: The Hydro-Wiper reduces the need for costly site visits to manually clean the instrument, maintaining data integrity throughout long deployments.

Proven in the field:   Zebra-Tech has created a range of models that are now being used by educational institutions, government agencies and private companies in all parts of the world.

Self-contained Hydro-Wiper

Ideal for extended deployments of sensors where external power supplies are not available. The wiper unit is connected to a rugged underwater housing that contains the batteries, control electronics, diagnostic LED and wipe interval select switch.

Powered by 6 user replaceable alkaline batteries, the Hydro-Wiper will operate for over 4 months with a 1 hour wiper interval. The wipe interval can be set from 15 minutes to 12 hours, to suit the environment. A high precision on-board clock ensures time drift during long deployments is minimal.

The Data-logger controlled Hydro-Wiper consists of a wiper unit that is attached to your sensor or underwater camera by a purpose designed clamp.

The wiper unit is connected to the Hydro-Wiper control module by an electrical cable. The control module is a small rugged wiring panel that connects to a power supply and a data logger. To initiate a wipe, the data logger simply sends a trigger signal to the control module.

Synchronizing the wipe with measurements from the instrument ensures data quality is consistent throughout the deployment and optical sensor fouling is minimized.

Hydro-Wiper Integration with Camera Housing.

Underwater camera need a clean?

The Hydro-Wiper can be customized and has been used successfully in a variety of underwater camera installations. Look at some of our recent designs.

Camera Housings

Often providing a solution for an underwater camera deployment requires some customization so please talk to us about your needs.

A custom housing?

If you are still looking at underwater camera housing options, Zebra-Tech collaborates with  MDEL (Marine Design Engineering Ltd) to provide an integrated housing and Hydro-Wiper for your underwater camera system. Read more here or Contact Us for more information.

Lighting

Underwater lighting is also prone to bio-fouling and we have experience customizing solutions for those too.
