Clean optical sensors and underwater cameras

“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 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: Developed in 2007, Hydro-Wipers have been deployed in some of the harshest environments by educational institutions, research organisations, government agencies and private companies in all parts of the world.

Standard models: From flourometers to turbidity sensors, dissolved oxygen instruments to nitrate analyzers, PAR sensors and more, we can wipe them!

Custom design: We can provide custom clamps, brushes and cable lengths, power and triggering options, and depth ratings. Please contact us to discus your requirements

Features

ZebraTech Hydro-Wipers are designed and built to last, even in the harshest environment.

Hydro-Wipers use a special custom designed brush that has over many years and thousands of deployments, proven to keep delicate windows clean without causing scratching or damage.

The park position and wipe angle can both be easily adjusted to suit the instrument installation.

All Hydro-Wipers feature “fail-safe” technology to ensure successful long term deployments. If the brush arm is bumped or forced, the Hydro-Wiper will automatically reset the brush arm position back to the park position.

If the brush arm is jammed, for example with rope entanglement, the Hydro-Wiper is not damaged. Instead it periodically tries to untangle itself.

Need to wipe multiple instruments? No problem. We can supply custom brushes and clamps for up to 3 instruments onto a single Hydro-Wiper.

Hydro-Wipers have a 30m depth rating as standard, with 100m options available.

Self-contained Hydro-Wipers

Ideal for extended deployments 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, wipe angle controls, and wipe interval select switch.

Powered by six user-replaceable alkaline batteries, the Hydro-Wiper will operate for over 6 months with a 1 hour wiper interval. For extended deployments, a larger battery housing is available.

The wipe interval can be set from 15 minutes to 12 hours, to suit the environment.

Data-logger controlled Hydro-Wipers

The Data-Logger controlled Hydro-Wiper uses your power supply and wipe trigger signal to control the wipe.

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

Talk to us to discus how easy it is to integrate a Hydro-Wiper into your instrument setup.
