In-Situ Aqua TROLL 400 MP

Robust and compact - the Aqua TROLL 400 is the smallest and most affordable of the In-Situ multiparameter probes. It is ideal for monitoring standard water parameters for a variety of environmental applications in freshwater, seawater and wastewater. Up to 12 parameters can be measured with the permanently installed sensor set. The AquaTroll 400 can be easily connected to an external data logger, sampler, SCAD/PLC system or telemetry device via open communication protocols. For use as a mobile probe, the AquaTroll 400 is best used with the Wireless Troll readout device incl. battery pack.   

Measurement parameters

  • Temperature
  • Actual and specific conductivity, salt content, dissolved solids content, resistance, density
  • Dissolved oxygen with optical measurement: In-Situ patented and EPA-approved Rugged Dissolved Oxygen (RDO technology, automatic temperature compensation f)
  • pH value (sensor is interchangeable)
  • Redox potential
  • Pressure sensor (absolute pressure)

In-situ platform

The AquaTroll 400 has the usual advantages of the in-situ measuring platform: simple and low-maintenance use and calibration of the probes, and the proven corrosion-resistant probe design with titanium protective cage.  The extremely stable and length-true Rugged Troll cables with the patented titanium bayonet connectors are available in any length and can also be subsequently coupled/extended using the Rugged Cable Splitter/Cable Extender.

The user-friendly free VuSitu app for Android/Apple provides instant data, graphs, measurement logs, GPS coordinates and auto-calibration function, as well as simplified routines for log setup or creating sampling protocols.
