Aqua TROLL 400 multi-parameter probe
Introduction: A compact, durable multi-parameter process probe that can continuously measure 12 water quality parameters for multiple applications. The standard kit consists of 6 sensors that measure actual and specific conductivity, salinity, total dissolved solids, resistivity, density, optical dissolved oxygen, ORP, pH, temperature, water level, and water pressure.
Features:
The sensor adopts NIST tracking standard (where applicable) and is calibrated by the manufacturer
DO reading automatically compensates for salinity
Multiple power options and real-time readings
Easy installation, reduce errors and debugging time, improve efficiency
Long-term calibration reduces the number of visits to the site
Modbus/RS485 or SDI-12 protocol
Real-time access to data via radio, controller, data recorder, sampler, telemetry system or SCADA/PLC system
Application range:
Storm management
