Advanced Cl2-pH-ORP controller with precise PID Control, 2 set points, 2 relay contacts, wall mounted, CL3050

The CL3050 is an advanced multi-parameter controller for the accurate measurement and control of free, combined and total chlorine, pH, ORP (redox) and temperature. 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 controller is suitable for a wide range of applications, including water treatment, swimming pools, drinking water systems and the food industry.

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
