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.

BASE KIT INCLUDES AQUA TROLL INSTRUMENT

(including press, temp, cond, RDO, ph/ORP sensors)

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, and DO and Level readings are automatically compensated for barometric pressure

Applications: • LONG-TERM GROUNDWATER AND SURFACE WATER MONITORING

• COASTAL DEPLOYMENTS—ESTUARIES AND WETLANDS

• REAL-TIME WATER QUALITY MONITORING NETWORKS

• REMEDIATION AND MINING • STORMWATER MANAGEMENT
