In-Situ Aqua TROLL 800

The Aqua TROLL 800 is a powerful multi-parameter probe with internal logger and battery supply. Like the AquaTroll 700, it has 6 sensor slots and is therefore ideally suited for demanding measurement applications with many parameters in surface and coastal waters, as well as e.g. for tracer experiments with simultaneous monitoring of field parameters in GW measuring points or spring discharges.  

With a typical battery life of 6-9 months (readout interval 15 min, with/without wiper), the corrosion-resistant design and optional anti-fouling, it is ideally suited for long-term monitoring - as a stand-alone logger or together with the VuLink telemetry unit

Thanks to the integrated Bluetooth® interface, the AT800 can also be used as a field device for spot checks or profile measurements. 

Probe features

- LCD display for visual inspection of battery, sensor and memory status. 

- Integrated Bluetooth interface, RS-485/MODBUS, SDI-12  

- Field-proven design with corrosion-resistant housing. Two-sided titanium protective cage serves as a storage cap/ 50 mL calibration cup. 

Low calibration effort due to drift-stable sensors 

Space-efficient - for use with 6 sensors, with a diameter of only 7.2 cm. 

Versions: with vented/ unvented/ without pressure sensor in the probe body. for various pressure ranges up to 200 m.   

See data sheet for measuring ranges and accuracy of the sensors.  

 
- Optional anti-fouling system: The programmable double-sided anti-algae wiper integrated in the probe head automatically cleans all sensors for reduced maintenance and longer service life. The protective basket with copper coating serves as a passive anti-fouling system. 

In-situ platform 

The AquaTroll 800 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 easy-to-use free VuSitu app for Android/Apple provides instant data, graphs, measurement logs, GPS coordinates and auto-calibration, as well as simplified routines for log setup or creating sampling protocols.  

The Troll range combines market-leading water quality sensors with smartphone mobility by allowing you to collect and analyze data using the VuSitu Mobile app on your Android™ device. Alternatively, data can be read out via the Win-Situ Windows software on a PC or via the HydroVU Online Portal. 

The AquaTroll probes can be flexibly equipped with the market-leading, drift-resistant in-situ smart sensors. The calibration is stored directly on the sensor head. This means that the sensors can be inserted into any AquaTroll 500 - 800 in any slot with a flick of the wrist and used immediately. The robust sensors can be replaced quickly and easily, even when wet.
