Long-term monitoring / spot measurement of water quality

Aqua TROLL 500 is a robust and high precision multi-parameter probe for the punctual or continuous monitoring of standard physico-chemical parameters in water.

  • Designed for maximum durability in any application
  • Suitable for all applications: Fresh water - Salt water / Surface water - Ground water >> Point measurements / Long term deployment
  • Very low energy consumption: up to 9 months of autonomy for a measurement every 15 minutes (AquaTROLL 600)
  • Low maintenance: stable sensors, low long-term drift
  • Fully customizable probe: choose only the sensors and accessories (anti-fouling, cables, modems, ...) you need!

Reliability and robustness

The Aqua Troll 500 multi-parameter probe consists of a titanium probe body and customizable sensors that are robust, reliable and accurate

adapted for use in the most hostile environments (corrosive environments, fresh or salt water...)

The probe is equipped with an LCD screen, allowing to quickly visualize the current status (status of the sensors, status of the bluetooth connection...)

Its reduced dimensions allow its use in drillings from Ø 2''.

One-time measurement or long-term monitoring

The Aqua TROLL 500 probe has been designed for two types of use:

Point measurement

Coupled with the bluetooth communication kit

TROLL Com, you have a robust multi-parameter point measurement device with interchangeable sensors. Thanks to the dedicated mobile application, VuSitu (Android), let yourself be guided to configure the instrument, access and download the data in real time.

Long-term monitoring

Its Modbus RS485 and SDI-12 output signals also allow the Aqua TROLL to be connected to most telemetry systems (PLC / SCADA) and PLCs for remote monitoring. The probe can also be connected to a simple data a simple data logger.

Compatible with Tube300 / Cube300 GSM/GPRS modems and HydroVu web portal for near-instantaneous data monitoring from your office.
