Aqua TROLL®
Multiparameter Sondes
THE AQUA TROLL 500, 600, 700 AND 800 ARE FULLYCUSTOMIZABLE MULTIPARAMETER SONDES WITH
INTERCHANGEABLE SENSORS AND SMARTPHONE
INTERFACE THAT DELIVER ACCURATE DATA AND ENABLE
SIMPLIFIED CALIBRATION, PANORAMIC DATA AND REPORTCREATION.
These flexible instruments are ideal for spot checking and profiling whenpaired with a Wireless TROLL Com and the VuSitu app, and for continuous,
remote monitoring when used with VuLink telemetry and HydroVu dataservices.

The Aqua TROLL 500 and 600 are five-port multiparameter sondes,including four sensor ports and a wiper port. The Aqua TROLL 700 and800 are seven-port multiparameter sondes, including six sensor ports anda wiper port. There is an option to have an automatic antifouling wiper toensure data accuracy.

All four sondes are available in vented and non-vented options and arecompatible with the complete range of Aqua TROLL sensors.

A SHARED ECOSYSTEM
Reduce complexity and cost with equipment that works together. AllAqua TROLL products use the same ecosystem—from handheld tocable to communication.

3D FACTORY CALIBRATION
In-Situ performs a multi-point factory calibration on every sensor,

to ensure that the sensor is linear across its full range and simplify
calibration for the user.
LOW-MAINTENANCE DEPLOYMENTKeep labor and equipment costs down with advanced passive andactive antifouling on all sensors and 6+ month battery life.
ENHANCED RELIABILITY
In-Situ equipment is designed to withstand use in the harshest

environments. Features designed to prevent breakage or failure
include:• Interlocking sensors for greater stability• Titanium restrictor• Fully potted sensors• Redundant SD card storage• Multi-chamber design

BUILT-IN ERROR PREVENTION
Prevent the most common damage or loss with:• Spring-loaded screws that keep screws in place• Slip-clutch wiper to prevent motor damage• Smart sensors that fit in any port

• Wet-mate connectors that prevent water damage• Anti-roll bumpers to keep equipment stationary
MINI CALIBRATION CUP
These sondes use only 50 ml (Aqua TROLL 500/600) and 100 ml (AquaTROLL 700/800) of solution for calibration, reducing calibration costby 5x over traditional methods and saving thousands of dollars incalibration solution per year.

FAST-RESPONSE SENSORS
Aqua TROLL sensors were designed to support spot-checking andprofiling applications where sensor response time is critical. The
temperature sensor uses an extended thermistor and insulatedbarriers; RDO® has optional fast-response formulation; and a roundbulb increases surface area and improves response time on the pHsensor.

Two Alkaline D-cell batteries provide internal power
to the instrument for continuous deployment (6+months depending on logging rates and wiper)without external power
