Online PH Meter Pune – Digital pH Meter for Industrial Water Monitoring

UMA Industries supplies reliable Online PH Meter Pune
solutions for continuous measurement of acidity and alkalinity in water,
wastewater, chemical solutions and industrial process liquids. The
panel-mounted instrument is suitable for ETP plants, STP plants, RO plants,
DM plants, electroplating units, automotive factories, chemical industries,
textile processing, pharmaceutical utilities, food-processing plants,
cooling towers and boiler water-treatment systems.

Industrial Online PH Meter Pune

An Online PH Meter Pune receives the electrical signal from
a compatible pH electrode and converts it into a clear digital pH value.
Continuous measurement allows operators to observe process changes
immediately instead of depending only on periodic laboratory samples.

The pH scale normally extends from 0 to 14. A value below 7 indicates an
acidic liquid, 7 represents neutral conditions and a value above 7 indicates
an alkaline liquid. Correct pH monitoring supports wastewater neutralisation,
chemical dosing, corrosion control, treatment efficiency, product quality
and stable industrial operation.

Technical Specifications

The following are typical specifications for an
Online PH Meter Pune. Final specifications depend on the
selected model, electrode, output requirement and installation conditions.

Working Principle of an Online pH Meter

A pH electrode contains a sensitive glass membrane and a reference system.
When immersed in a process liquid, the electrode develops a small electrical
potential related to hydrogen-ion activity. The meter receives this signal,
applies the stored calibration values and displays the corresponding pH
reading.

The electrode can be installed in a treatment tank, neutralisation vessel,
pipeline, effluent channel, flow cell or sampling pot. The display unit is
normally mounted in an electrical panel where the operator can continuously
observe the live process value.

Models with relay outputs can activate alarms, pumps, valves or interlocks
when pH crosses a selected limit. Analogue-output and Modbus models can
transmit the measured value to a PLC, HMI, SCADA system, recorder or central
monitoring dashboard.

Difference Between an Online pH Meter and pH Controller

A standard online pH meter measures and displays the current pH value. A pH
controller performs the same measurement and additionally provides relay
outputs for automatic acid dosing, alkali dosing, alarm operation or plant
interlocking.

Select a basic meter when continuous indication is required. Select a
controller when the process must automatically correct high or low pH
conditions.

Calibration of Online PH Meter Pune

Regular calibration is essential for dependable operation of an
Online PH Meter Pune. Electrode ageing, chemical exposure,
scale, sludge, oil and other deposits can gradually affect sensor response.
Cleaning and calibration compensate for these changes.

Calibration Materials

• Fresh pH 7.00 buffer solution
• Fresh pH 4.00 buffer solution
• pH 9.18 or pH 10.00 buffer for suitable alkaline applications
• Clean distilled or demineralised water
• Separate clean beakers for every buffer solution
• Soft tissue for gently removing excess liquid
• Calibration and maintenance record sheet

Step-by-Step Calibration Procedure

1. Switch on the meter and allow the display to stabilise.
2. Remove the electrode carefully from the process tank, pipeline or flow cell.
3. Inspect the glass bulb, cable and BNC connector for damage or deposits.
4. Rinse the electrode with distilled or demineralised water.
5. Gently shake off excess water without rubbing the sensing bulb.
6. Immerse the electrode in fresh pH 7.00 buffer solution.
7. Wait until the displayed reading becomes stable.
8. Adjust the pH 7 calibration setting until the display shows 7.00.
9. Remove the electrode and rinse it again with clean water.
10. Immerse the electrode in fresh pH 4.00 buffer solution.
11. Wait for a stable reading and adjust the pH 4 calibration setting.
12. For alkaline-range measurement, use a suitable pH 9.18 or pH 10.00 buffer.
13. Rinse the electrode and recheck it in pH 7.00 buffer.
14. Reinstall the sensor and verify the live process reading.
15. Record the date, buffer values and final calibration readings.

Recommended Calibration Frequency

Clean-water systems may be checked weekly, fortnightly or monthly according
to plant practice. Wastewater, sludge, electroplating solutions, oily liquids
and aggressive chemicals may require more frequent cleaning and calibration.
Replace the electrode when it becomes very slow, continuously unstable or
impossible to calibrate correctly after cleaning.

Selecting the Correct pH Electrode

compatibility, contamination, suspended solids, mounting arrangement and
cable length.

• General-purpose glass electrode for clean water
• Industrial immersion electrode for tanks and sumps
• Flow-through electrode for pipelines and sample chambers
• Double-junction electrode for contaminated process liquids
• Flat-surface electrode for viscous materials

Installation Guidelines

Correct installation of an Online PH Meter Pune helps
reduce unstable readings, premature electrode failure and inaccurate process
data.

1. Install the meter inside a clean, dry and ventilated control panel.
2. Protect the instrument from water spray, corrosive fumes and excessive heat.
3. Install the electrode where the liquid is representative and properly mixed.
4. Avoid mounting the sensor directly beside an acid or alkali injection point.
5. Keep the glass sensing bulb immersed during normal operation.
6. Avoid locations where air bubbles collect around the electrode bulb.
7. Keep the electrode cable away from motors, VFDs and high-voltage wiring.
8. Provide proper panel earthing to reduce electrical noise.
9. Use a suitable flow cell when direct tank installation is not practical.
10. Provide sufficient space for electrode removal, cleaning and calibration.

Maintenance and Safety Precautions

• Never allow the pH electrode glass bulb to remain dry.
• Store the sensor in the recommended electrode-storage solution.
• Do not permanently store the electrode in distilled or DM water.
• Do not clean the glass bulb with abrasive tools.
• Use fresh and uncontaminated buffer solutions.
• Never return used buffer solution to its original container.
• Clean oil, sludge, scale and chemical deposits regularly.
• Inspect the sensor cable and BNC connector for moisture or damage.
• Keep chemical leakage away from the electrical panel.
• Use suitable PPE while handling acids, alkalis and process chemicals.
