pH ORP Sensor Measurement Principle

قياس الأس الهيدروجيني

The pH sensor measures hydrogen ion activity using a glass electrode and reference electrode.
The potential difference generated between the electrodes varies proportionally with the pH value of the solution.

ORP Measurement

ORP measurement is based on detecting the oxidation or reduction potential of the solution.
The sensor outputs a millivolt (mV) signal representing the solution’s ability to gain or lose electrons.

Both signals are digitally processed and transmitted via RS485 for stable and accurate readings.

pH ORP Sensor Installation & Integration

Immersion, pipeline, or flow-cell installation
Plug-and-play with Instrava water quality analyzers
Compatible with PLC, SCADA, and DCS systems
Suitable for continuous online monitoring

What is the typical service life of a pH or ORP electrode in industrial applications?

Under normal industrial water conditions, the typical service life of a pH or ORP electrode is 12–18 months. Actual lifespan depends on water quality, temperature, chemical composition, and maintenance practices.

How often should the pH ORP sensor be calibrated?

For stable industrial water, calibration is usually recommended once per month. In harsh or fluctuating process conditions, more frequent calibration (every 1–2 weeks) helps maintain measurement accuracy.

What factors most commonly reduce electrode lifespan on site?

Electrode lifespan can be shortened by high temperature, strong acids or alkalis, oil contamination, solids abrasion, and improper cleaning. Regular inspection and correct cleaning procedures significantly extend sensor life.

Can the pH ORP sensor be used directly in wastewater with suspended solids?

Yes. The sensor is suitable for wastewater applications; however, regular cleaning is recommended to prevent fouling on the glass membrane, which may affect response time and accuracy.

Is the sensor compatible with different transmitters or controllers?

The pH ORP sensor is compatible with most standard industrial pH/ORP transmitters and analyzers that support glass electrode inputs and NTC temperature compensation.

How can stable measurement be ensured in long-term online operation?

Stable long-term operation is achieved through proper installation, correct calibration, regular cleaning, and suitable electrode selection based on process conditions. Using compatible transmitters with temperature compensation further improves measurement stability.
