EC3000 Conductivity Sensor

The EC3000 provides a self-contained monitoring and data logging system for a wide range of water monitoring applications, including tidal and estuary monitoring. Stable, accurate and repeatable readings in the field are ensured with multi-point linearity and temperature calibration over the full operating ranges.

The robust and reliable toroidal sensor for conductivity measurement and a thermistor for temperature measurement combine with the rugged acetal housing and double O-ring design to make the unit ideal for use in the harshest environmental conditions. An internal logger provides long term data collection, as well as providing options for remote telemetry. The unit can be powered via an external cable, or with an onboard battery pack for true stand alone operation. An optional cable can provide SD12 output for connection to a process controller or external logger.

The EC3000 is a cost effective long-term pH monitoring solution that is both easy to use and configure using the supplied Smartcom software.
