pH / ORP Controller

Industrial pH and ORP Controllers for Continuous Process Monitoring

Tenber industrial pH and ORP controllers are designed for continuous liquid-analysis applications in water treatment, chemical dosing, electroplating wastewater and industrial process control. Available configurations include verified 4–20mA output, relay control and RS485 Modbus RTU communication on selected models for connection to compatible PLC, SCADA and data-acquisition systems.

Choose the Controller Around the Real Process

A reliable measurement system depends on more than the controller display. The measuring range, liquid composition, temperature, pressure, installation method, cable length, output signal and control requirements should all be confirmed before selecting the controller and electrode. Tenber provides application-based model selection so that the instrument, sensor and signal configuration match the actual operating conditions.

PH-301

A practical online pH/ORP controller with verified 4–20mA output for wastewater treatment, environmental monitoring, fermentation and process-water applications.

PH-302

An industrial pH/ORP controller for projects requiring online measurement, relay functions and RS485 Modbus RTU communication on the selected configuration.

PHS-3301

A high-accuracy controller platform with isolated current output and RS485 Modbus RTU for industrial monitoring and automation integration.

Typical Applications

• Wastewater neutralization: continuous pH measurement for acid and alkali dosing, treatment and discharge monitoring.
• Electroplating and surface treatment: pH or ORP monitoring for chemical dosing, rinse-water control and wastewater treatment after the correct electrode is confirmed.
• Chemical processing: stable measurement for reaction control, dosing and process supervision.
• Water treatment systems: online pH monitoring for pretreatment, RO, drinking water and industrial process water.
• Automation integration: connection to compatible PLC and SCADA systems using the required analog or digital output.

Controller and Electrode Selection

The electrode must be selected according to the medium. Strong acid, strong alkali, oil, suspended solids, high temperature and chemical contaminants can require different glass membranes, junctions, body materials and installation arrangements. Send the liquid composition and operating conditions with your inquiry so that Tenber can check the complete controller-and-electrode combination.

Frequently Asked Questions

Can a Tenber pH controller connect to a PLC?

Selected models provide 4–20mA output or RS485 Modbus RTU. Confirm the PLC input, required channels and communication settings before ordering.

Can these controllers be used for electroplating wastewater?

Yes, they can be considered for pH and ORP monitoring, but the electrode must be matched to the chemicals, temperature, pressure and installation conditions.

What information is needed for model selection?

Please provide the application, liquid, measuring range, temperature, pressure, installation method, output signal, power supply, cable length and required quantity.

Do you provide after-sales support?

Tenber provides English documentation and responsive assistance for wiring, calibration, communication settings, maintenance and troubleshooting.
