High-Capacity Workhorse

Manta Plus 35 Multiparameter Probes

Available in Manta +35A and +35B configurations, both models come standard with turbidity, temperature, pH, conductivity, and dissolved oxygen. Engineered for extreme capacity, the 35 series supports up to 3 fluorometers simultaneously.

Manta+ 35 Multiparameter Water Quality Sonde

Water Quality Sondes

The Manta +35 model features an optical DO sensor with a 5+ year cap and a refillable pH reference, ensuring a low cost of ownership. Connect to field displays, add battery packs for autonomous use, or link to telemetry for real-time cloud data.

Multi-Fluorometer Support

Unique ability to hold up to 3 fluorometers simultaneously, perfect for advanced oceanographic and limnological studies. Monitor Chlorophyll, Blue-Green Algae, and FDOM in one go.

Extensive Parameter Suite

Monitor up to 12 parameters simultaneously with our high-density sensor integration technology.

9-Port Configuration

Optimized port spacing allows for larger sensors without compromising the compact form factor of the sonde.

Advanced Data Logging

4 Mbytes of internal memory stores over a million readings, supporting long-term, high-frequency sampling for critical research projects.
