Manta+ 25 Multiparameter Water Quality Sonde

Water Quality Sondes

The Manta +25 features a refillable pH reference that eliminates expensive consumables, ensuring a low cost of ownership. Connect to our field display options, add a battery pack for autonomous use, or integrate with a telemetry station for real-time data in the cloud.

Data Integrity with Anti-Biofouling

Integrated wiper system ensures clean optical sensors for accurate long-term data. This reduces the frequency of site visits and ensures your data is never compromised by sediment or growth.

Self-Cleaning Wiper

Automatically cleans sensors to prevent biofouling in high-sediment or nutrient-rich environments, ensuring stable readings over months of deployment.

6-Port Configuration

Versatile port layout allowing for multiple high-impact sensors in a compact sonde, providing a comprehensive water quality profile.

Cloud Real-Time Telemetry

Connect to the cloud for real-time monitoring and data visualization from anywhere in the world. Get instant alerts and manage your network remotely.
