Product Description
Description
Protos II 4400 provides modular four-wire analysis of pH, ORP, conductive or inductive conductivity, and oxygen. It accepts Memosens, analog, and ISM or other digital sensors. Memosens configurations support four parameter inputs in any combination.
Features and control options
- Combine measuring, control, and communications modules to suit the application.
- Choose analog, digital, relay, and PID outputs, including standard 4–20 mA signaling.
- EtherNet/IP and PROFINET options deliver measurements and diagnostic information to control systems.
- Supports PID loops and Knick automated cleaning and calibration systems.
- Memory-card functions include recording, firmware updates, and audit trails.
Sensor condition and maintenance
SensoFace gives a quick indication of measurement-loop condition. A sensor diagram presents a broader health assessment. Wear, operating time, and load information support maintenance planning, while diagnostic icons identify service needs.
Operation and modular configuration
The high-resolution graphical LCD uses icons, guided menus, error explanations, and troubleshooting assistance. A soft-key favorites menu speeds access to frequent functions, and four measurement parameters can appear together. The modular architecture allows input and output combinations to be tailored to individual pH/ORP, conductivity, or oxygen processes.
