Advanced EC-pH-ORP-ISE controller with precise PID Control, 2 set points, 2 relay contacts, wall mounted, EP3050

The EP3050 is an advanced multiparameter controller for the precise measurement and control of EC, pH, ORP (Redox), and ISE (Cl-, NO3-, NH4+, Ca++). Thanks to the integrated PID control, the measured values are continuously monitored and automatically corrected, ensuring stable water quality even under varying process conditions.

The flexibility of use of the various types of sensors make the instrument suitable for many applications and types of systems.

Manual and automatic temperature compensation are available when an RTD Pt100 or RTD Pt1000 is connected. When an RTD sensor is connected, the instrument also displays the measured temperature.

The instrument offers:
- Display of the measurement within the range of the installed sensor
- Automatic measurement check function
- Alarm in the event of min/max values being exceeded, excessive relay activation or the presence of logic inputs
- Dual programmable analogue output for data logging or PID control
- Hold/alarm function activated via two external potential-free contacts
- Automatic or manual autoclean function
