The Aqua TROLL 400 Multiparameter Instrument is ideal for long-term groundwater and surface-water applications. The instrument leverages our patented, EPA-approved RDO® Technology. The compact instrument houses six water quality sensors and measures 12 parameters:

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

Applications

  • Coastal deployments
  • Long-term surface-water monitoring—gaging stations and reservoirs
  • Long-term groundwater monitoring
  • Real-time monitoring networks
  • Remediation and mining
  • Stormwater management

Confidence in Your Data

  • Field-tested sensor technologies lower your total cost of ownership by providing stable, accurate results.
  • Sensors are factory calibrated 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 & 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, or SCADA/PLC system.
  • Long-lasting calibrations reduce site visits.
  • The narrow-diameter instrument operates in fresh, marine, and process waters.
