The Aqua TROLL 500 is a fully customizable five-port multiparameter sonde with capacity for four interchangeable sensors plus an antifouling wiper. A smartphone interface delivers accurate data and enables simplified calibration, panoramic data view, and report creation. Ideal for spot-checking and profiling with a TROLL Com Plus, or long-term monitoring with VuLink telemetry.Corrosion-resistant titanium construction stands up to harsh environments, and a convenient LCD readout of sensor health and connectivity gives you confidence in your deployment. Sensor options include temperature, conductivity, pH/ORP, Rugged Dissolved Oxygen (RDO), turbidity, chlorophyll a, phycocyanin (BGA-PC), FDOM, chloride, and nitrate.Why it works Shared ecosystem. All Aqua TROLL products use the same handhelds, cables, and telemetry, which reduces complexity and cost. 3D factory calibration. Every sensor gets a multi-point factory calibration so it is linear across its full range, simplifying user calibration. Low-maintenance deployment. Sub-2-inch passive and mechanical antifouling on all sensors keeps it reliable for long deployments in fresh and saltwater. Mini calibration cup. Uses only 50 mL of solution for rinsing and calibration, cutting calibration cost roughly 5x versus traditional methods. Built-in error protection. Spring-loaded screws, a slip-clutch wiper, smart sensors that fit any port, wet-mate connectors, and anti-roll bumpers prevent the most common field damage. Fast-response sensors. Designed for spot-checking and profiling where response time is critical. Cable, TROLL Com Plus, and VuLink sold separately.
