pH Controller in Asansol
pH Controller in Asansol is an industrial instrument used for continuous measurement and automatic control of the acidity or alkalinity of water, chemical solutions, cooling water, process liquids and industrial effluent. UMA Industries supplies digital pH controllers, online pH meters, pH indicators, pH electrodes and industrial water-quality instruments for steel plants, coal washeries, mining industries, thermal power plants, engineering units, chemical plants, ETP/STP systems and RO plants.
The controller receives the measurement signal from a compatible pH electrode, displays the current pH value and operates relay outputs according to the configured set point. The relay output can control an acid-dosing pump, alkali-dosing pump, alarm, solenoid valve, contactor or process interlock.
Models are available with one relay, two relays, dosing delay, analysis time, 4-20 mA output, 0-10 VDC output and RS485 Modbus communication for PLC, HMI, SCADA and data-logging integration.

How a pH Controller Works
The pH electrode senses the acidity or alkalinity of the process liquid and sends a low-level electrical signal to the controller. The controller converts the signal into a digital pH value and compares it with the selected set point.
When the measured pH crosses the configured control limit, the appropriate relay operates. This relay can control a dosing pump, solenoid valve, alarm, interposing relay or contactor.
In a two-relay model, one relay can be used for acid dosing and the other for alkali dosing. The control direction, hysteresis and dosing sequence must be verified according to the process requirement.
Acid and Alkali Dosing Control
Acid-Dosing Operation
When the measured pH is higher than the required set point, the acid-dosing relay may operate to reduce the pH. The relay switches OFF after the pH returns to the configured control range.
Alkali-Dosing Operation
When the measured pH is lower than the required set point, the alkali-dosing relay may operate to increase the pH. The relay switches OFF after the required pH range is achieved.
Always verify the dosing chemical, relay-control direction, pump capacity and electrical load before commissioning the system.
Calibration Procedure for pH Controller
Prepare the pH Electrode
- Switch ON the pH controller and allow the reading to stabilise.
- Remove the electrode from its storage solution.
- Rinse the electrode gently with clean or distilled water.
- Shake off excess water without touching the glass sensing bulb.
Calibrate at 7.00 pH
- Dip the electrode into fresh 7.00 pH buffer solution.
- Wait until the displayed reading becomes stable.
- Adjust the 7 pH calibration control slowly.
- Set the display to exactly 7.00 pH.
Calibrate at 4.00 pH
- Remove the electrode and rinse it with clean water.
