PH6.0 pH Controller, ORP Controller, Online Liquid Monitoring for Industry and Laboratory
Introduction
This intelligent online liquid analyzer stands out as a refined solution, leveraging two decades of expertise to deliver seamless integration into industrial settings. Its switchable functionality allows instant toggling between pH and ORP modes without hardware changes, accommodating both combination electrodes and split configurations for flexible sensor pairing.
The built-in pH sensor excitation supply simplifies connections, while the setup program enables intuitive configuration of alarms, outputs, and calibration routines. With low power consumption (≥6W) and robust signal transmission for remote SCADA or PLC systems, the PH6.0 pH control and monitor instrument ensures uninterrupted data logging and process optimization, reducing operational risks in variable-temperature applications.
Working principle
Step 1: The PH6.0 pH/ORP Controller processes signals from connected electrodes to compute real-time values.
For pH mode, it amplifies the millivolt potential from the glass membrane against a stable reference, applying temperature corrections to yield the final reading.
In ORP mode, it directly interprets the redox potential difference.
Step 2: Incoming data passes through high-impedance amplification (≥10¹² Ω) to preserve signal integrity, followed by digital conversion and compensation algorithms that adjust for thermal influences.
Step 3: Outputs are scaled linearly, e.g., 4-20 mA proportional to the measured range, triggering relays for setpoint-based control, all processed via embedded Modbus-RTU for networked oversight.
