With interchangeable sensors, the Aqua TROLL 500 replaces multiple instruments and saves time in the field to reduce overall monitoring costs. Highly stable sensors need minimal maintenance and calibration, giving you confidence in your data. Just plug the sonde into a Wireless TROLL Com, datalogger, control system or telemetry and you’re ready to go!

The Aqua TROLL 500 fits a wide variety of applications, including:

• Surface water spot sampling and profiling

• Remote monitoring via telemetry

• Long-term drinking water, wastewater or stormwater monitoring

• Aquaculture

• Low-flow groundwater sampling and remediation

 

Features

• Base sensor configuration includes EPA-approved optical RDO, pH/ORP, turbidity, conductivity, temperature, and pressure, Salinity, resistivity, Total Dissolved Solids (TDS) and Density

• Long-term pH stability: the Aqua TROLL 500 pH change is 0.0008 pH/day, or a change of 0.1 pH in 125 days. Learn more »
