Aqua TROLL 700 Multiparameter Sonde
Seven-port sonde for expanded parameter counts in surface water
Aqua TROLL 700 Multiparameter Sonde
A fully customizable, seven-port multiparameter sonde with capacity for six interchangeable smart sensors and a wiper. Built for spot checking, remote monitoring, and long-term deployment in surface water, coastal, and groundwater applications where more parameters — algae pigments, nutrient ISEs, dye tracers — are needed at once.
- Up to 6 smart, field-interchangeable sensor ports plus a motorized wiper port
- Onboard internal memory and micro SD card backup logging
- Sub-3-inch mechanical antifouling on all sensors, 9+ month maintenance intervals
- Bluetooth pairing with the VuSitu mobile app for calibration and live data — requires a TROLL Com Plus or Wireless TROLL Com (sold separately)
- Pairs with TROLL Com Plus for spot-checking or VuLink telemetry for long-term monitoring
- Available in vented and non-vented configurations
- Operating temperature: -5 to 50 °C
