ZebraTech Hydro-Wiper – Automatic cleaning for underwater sensors

This ensures consistent measurement accuracy while significantly reducing the need for manual cleaning and costly maintenance visits.

Key Features

Effective anti-fouling solution
Prevents contamination of optical surfaces caused by biofouling, sediment and deposits

Gentle and safe cleaning
Specially designed brush protects sensitive sensor surfaces from damage

Automatic operation
Configurable cleaning intervals or control via datalogger

Reliable long-term data
Maintains measurement accuracy during extended deployments

Robust design
Suitable for both freshwater and marine environments

Flexible integration
Compatible with a wide range of sensors and monitoring systems

Operation

The Hydro-Wiper uses a mechanical brush that periodically sweeps across the optical surface of the sensor. This prevents the buildup of fouling and ensures a clean measurement window.

Cleaning can be:

• performed automatically at preset intervals
• or synchronized with measurement cycles via a datalogger

This synchronization ensures consistent and reliable data throughout the deployment period.

Versions

Standalone version

• Battery powered
• Adjustable cleaning intervals (e.g. 15 minutes to 12 hours)
• Ideal for remote or off-grid locations

Datalogger-controlled version

• Controlled via external systems
• Synchronization with measurement events
• Optimized data quality and control

Why Automatic Cleaning is Essential

During long-term water monitoring, sensor fouling is inevitable and leads to:

• measurement drift
• reduced accuracy
• unreliable data

The Hydro-Wiper prevents these issues and ensures:

• stable and accurate measurements
• reduced maintenance and operational costs
• longer deployment periods

Applications

The Hydro-Wiper is ideal for:

Water quality monitoring
Research and development (R&D)
Offshore and marine applications
Environmental monitoring
Aquaculture
Hydrological monitoring networks

Compatible with:

PAR sensors
Turbidity sensors
Fluorometers
Dissolved oxygen sensors
Underwater cameras

Integration & Flexibility

The Hydro-Wiper can be easily integrated into existing monitoring setups thanks to:

• custom mounting options
• multiple power configurations
• multi-wiper configurations for multiple sensors
• application-specific customization
