Description

The is a precision online pH/ORP and temperature controller designed for continuous monitoring and control in water treatment, chemical processing, aquaculture, and industrial applications. Built for panel mounting, it integrates high-accuracy measurement, process control outputs, and user-configurable alarm settings in a compact, robust design.

The controller supports both pH and oxidation-reduction potential (ORP) measurement, with temperature compensation via a Pt100 sensor. It provides analog (420 mA) and relay outputs, making it ideal for integration with process control systems like PLCs or SCADA.

Key Features

  • Multi-parameter monitoring: Measures pH, ORP, and temperature simultaneously.

  • High accuracy and stability with advanced microprocessor-based circuitry.

  • 420 mA isolated output for process control or data logging integration.

  • Dual relay control outputs for activating pumps, valves, or alarms.

  • Automatic temperature compensation (ATC) using Pt100 sensor input.

  • Configurable alarm limits (HH, H, L, LL) with hysteresis to prevent relay chattering.

  • Bright LCD display for clear, real-time readings.

  • Panel-mount design suitable for industrial control panels.

  • Versatile power options available in both AC and DC models.

  • Low maintenance and easy calibration through user-friendly interface.

Applications

  • Water and wastewater treatment plants pH and ORP control in neutralization and disinfection processes.

  • Industrial process monitoring acid/alkali balance and oxidation control in chemical manufacturing.

  • Aquaculture and fish farming maintaining optimal pH and oxidation potential for aquatic health.

  • Swimming pools and spas continuous monitoring of water balance and sanitization levels.

  • Food and beverage industry quality control in fermentation and cleaning systems.

  • Environmental monitoring wastewater discharge compliance and pH control systems.
