Clear data. Fewer site visits. Built for harsh environments.

Bio-fouling and sediment build-up can quickly compromise optical sensor performance. The ZebraTech Hydro-Wiper is a rugged mechanical wiper system designed to keep optical windows clean, protecting data quality during long-term deployments in demanding environments.

Gentle cleaning, proven protection

A custom soft-brush design delivers regular, gentle cleaning without scratching or damaging delicate optical surfaces. Refined through thousands of field deployments, it reliably removes bio-fouling, mud and unwanted deposits.

Flexible fit, simple integration

With an adjustable wipe angle and park position, the Hydro-Wiper installs easily across a wide range of optical instruments. Standard and custom configurations make it suitable for everything from turbidity and PAR sensors to fluorometers and nutrient analysers – including the HOBO MX2502 Underwater PAR Sensor.

Built for unattended deployments

Designed for long-term reliability, the Hydro-Wiper includes fail-safe reset technology that automatically returns the brush to its park position if it is bumped or forced — ensuring continued operation without manual intervention.

Durable, adaptable and cost-effective, the Hydro-Wiper helps extend deployment durations, reduce maintenance visits, and maintain confidence in your data.

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 fluorometers to turbidity sensors, dissolved oxygen instruments to nitrate analyzers, PAR sensors and more, we can wipe them!

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.
• The Hydro-Wipers has a depth rating of 30m.

Self-Contained Hydro-Wipers

Ideal for extended deployments where external power supplies are not available. The Hydro-Wiper unit is connected to a rugged underwater Battery Housing that contains the batteries, control electronics, diagnostic LED, wipe angle controls, and wipe interval select switch.

Powered by six user-replaceable AA alkaline batteries, the Self-Contained Hydro-Wiper will operate for over 6 months with a 1-hour wiper interval.

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