The Aqua TROLL 600 is a powerful multi-parameter probe with internal logger and battery supply. Like the Aqua TROLL 500, it has 4 slots and can be flexibly equipped with the market-leading drift-resistant in-situ smart sensors. With the AT 600 you have all the options: Robust in groundwater and corrosion-resistant in surface water, 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 with your Android™ device (using the VuSitu Mobile app) and the internal battery, the AT600 is also an ideal field device for spot checks and sampling. 

Probe features 

- LCD display for visual check 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 
   
• The compact size enables use in level tubes from 5 cm / 2 inch diameter. 
   
• 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 into the probe head automatically cleans all sensors for reduced maintenance and a longer service life. The protective basket with copper coating serves as a passive anti-fouling system. 

In-situ platform 

The AquaTroll 600 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, the data can be read out via the Windows software Win-Situ on the PC or via the HydroVU Online Portal. 
Nitrate (ion-selective) 

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.
