Product Overview

The SUP-MDC-PH is an intelligent online pH/ORP controller designed for continuous monitoring and process control applications. It supports both analog and digital sensors, providing accurate pH and ORP measurement with flexible communication and output options. The controller can transmit measurement data through isolated 4–20 mA outputs or RS485 Modbus RTU communication for integration with DCS, PLC, and industrial monitoring systems. It is widely used in wastewater treatment, chemical processing, pharmaceuticals, food & beverage, environmental monitoring, and other industrial water quality applications.

Key Features

  • Supports both analog and digital pH/ORP sensors, allowing flexible sensor selection and easier maintenance.
  • Provides reliable measurement of pH, ORP, and antimony electrode signals with high stability for industrial process monitoring.
  • Features a 4.3-inch full-view color display with digital display and real-time curve modes, supporting up to 1,000,000 data records.
  • Supports manual and automatic temperature compensation modes including linear, acid, base, and pure water compensation.
  • Supports high/low alarm settings with adjustable hysteresis and delay functions for process control applications.
  • IP66 protection rating with flame-retardant housing suitable for harsh industrial environments.
