Healthy water Healthy fish Healthy profits Aqua TROLL® 400 Multiparameter Instrument Designed for aquaculture facilities, the Aqua TROLL 400 Seamless Integration Instrument eliminates complicated setup and provides instant access to water quality data. By leveraging proven technologies, interfaces with your current system. Connect the instrument like the optical RDO® Sensor, the instrument simplifies installation, calibration, and maintenance. The durable probe to a SCADA/PLC system or controller. • continuously measures 12 parameters: actual conductivity, specific conductivity, dissolved oxygen, ORP, pH, resistivity, With open communication protocols, the instrument easily For a local display, controller, and data logger, use the Con TROLL® PRO System (AC and DC models available). salinity, temperature, total dissolved solids, density, water level, To power the probe, use a SCADA/PLC system or the Con TROLL PRO System. Improved Risk Management • Outstanding Customer Service • Free application and deployment guidance Instrument continuously monitors and reports results in real Free, 24/7 technical support provides peace of mind time. You can respond quickly to changing conditions and Seven-day service for maintenance and calibration (U.S.A. only) maintain high operating efficiencies. • Operations can minimize fish stress, disease, and mortality by consistently controlling water quality. alarm notifications when water quality conditions deteriorate. • By connecting to a SCADA/PLC system, you will receive DO readings are automatically compensated for salinity and barometric pressure with a controller. Increased Productivity • One easy-to-use probe automates monitoring. Long-lasting calibrations reduce maintenance. Simplified installation reduces errors and training time.
