The MCT130 ORP Controller is a microprocessor-based water treatment controller. The controller can be used for pH and ORP control in cooling towers and boilers, and bio-retreatment for bio-lockout control.
The MCT130 ORP controller is a micro‑processor based water‑treatment controller that monitors and controls ORP levels, provides alarm indicators, and supports optional relay outputs and dry contacts. All inputs are fully insulated to eliminate ground loops and interference in industrial environments.
This manual covers the controller’s front‑panel overview, wiring, menu structure, configuration of analog and digital inputs, system calibration, programming parameters, and detailed troubleshooting steps, along with safety and FCC warnings. This manual is written in Chinese.
