Aqua TROLL 400 Multiparameter Probe

The Aqua TROLL 400 simplifies decision making with a fixed set of sensors that measure:

• Actual and specific conductivity, salinity, total dissolved solids, resistivity and density
• Dissolved oxygen (optical RDO®)
• ORP
• pH
• Temperature
• Water level and water pressure (absolute)

Rugged and compact, the Aqua TROLL 400 can be deployed for months of unattended operation in harsh field conditions. And because it’s easy to install and maintain, you save on training and reduced trips to the field.

Open communication protocols easily interface with your existing telemetry system. Access data anytime with a radio, controller, data logger, sampler, telemetry system, SCADA/PLC system, or HydroVu Data Services.

Leveraging proven technologies, like the patented, EPA-approved optical RDO® Sensor, the Aqua TROLL 400 decreases setup, calibration, and maintenance time. Ideal for long-term groundwater and surface water monitoring projects, you can deploy the probe for months of unattended operation. Partner with In-Situ to meet the challenges of reduced manpower and 24/7 demand.

Aqua TROLL 400 gives you CONFIDENCE IN YOUR DATA

• Field-tested sensor technologies lower your total cost of ownership and provide stable, accurate results.

• Receive 3D factory calibrated sensors that are validated with NIST®-traceable standards (where applicable).

• DO readings are automatically compensated for salinity. With the Con TROLL® PRO System, DO and level readings are automatically compensated for barometric pressure.

GREATER EFFICIENCY AND FLEXIBILITY

• Easy installation reduces errors and training time, while increasing productivity.

• With open communication protocols, the instrument easily interfaces with your current system. Access data anytime with a radio, controller, data logger, sampler, telemetry system, SCADA/ PLC system, or HydroVu™ Data Services.

• Long-lasting calibrations reduce site visits. • The narrow-diameter instrument operates in fresh, marine, and process waters.
