FAQs - pH Sensors

Why is pH important in water quality monitoring?

pH plays a critical role in determining whether water is safe, stable, and suitable for its intended use.
Incorrect pH levels can:
Harm aquatic life
Reduce the effectiveness of disinfectants like chlorine
Accelerate corrosion or scaling in pipes and equipment
Affect taste and odor of drinking water
Interfere with industrial and chemical processes
Because of these impacts, pH is one of the most frequently monitored water quality parameters worldwide.

What is pH sensor?

The pH sensor is a key instrument for determining pH levels and is widely utilized in water quality assessment. It measures the acidity or alkalinity of water and various solutions. When applied correctly, pH sensors help maintain the safety and quality of both products and operational processes, especially in wastewater treatment and industrial manufacturing environments.

How does pH sensor work?

When the sensor is placed in a liquid:
The hydrogen ions in the solution interact with the glass membrane.
This interaction generates a small voltage (electric potential) that changes depending on the pH of the solution.
The sensor compares this voltage to the reference electrode.
The resulting voltage difference is converted into a pH value by the transmitter or pH meter.

How to maintain the pH sensor?

If you want the pH sensor to keep in good condition, you must maintain the pH electrode regularly. Without proper maintenance, some common problems that may affect the electrode include: oily coating on the electrode, blockage or fouling of the reference contact, malfunction or breakage of the PH bulb, and short electrode life due to reference poisoning.

If the electrodes are usually coated with oil and other substances, consider using a sensor that includes a non-porous reference junction. The use of automated systems for cleaning electrodes can further reduce your maintenance needs. If the reference junction is often clogged or fouled, a non-porous electrode can also be used as a solution to this problem. If your pH bulb breaks when it comes in contact with sewage, you can use a bulb guard to protect it. As for the problem of reference poisoning, the use of non-porous electrodes can avoid these problems.

How to clean the pH sensor?

It only takes a few simple steps to clean your electrode to properly maintain and clean the pH electrode. Whenever handling pH electrodes, it is important to wear safety glasses and gloves. When the electrodes are not in use, they should always be kept in a liquid solution. If the electrode dries out, it can no longer be used. Most electrodes can only be purchased in saline solution, and you can continue to use them in the future.

In order to clean the electrode, you should put it in a solution consisting of 95% water and 5% hydrochloric acid. When the electrode is placed in this solution, most of the coating will dissolve. The sensor should be soaked for 5-10 minutes and then rinsed off. If the coating around the sensor is particularly heavy, the above steps should be repeated several times. Be sure to wipe the sensor with a soft cloth, as any abrasive cloth or brush will damage the electrode.

Why are different types of pH sensors important?

With modern water pollution becoming more and more serious today, it is urgent to protect the environment and protect water resources. Countries all over the world are paying attention to this issue. In some countries, industry is the backbone of the national economy. They know that it is not good to exchange economic development at the cost of the environment, but they have to do so. Therefore, water pollution is already a headache for the whole world. Sewage treatment equipment was developed under this background. Sewage treatment equipment can effectively treat domestic sewage and industrial waste water in urban areas to prevent sewage and pollutants from directly flowing into waters. PH sensor is an important part of sewage treatment equipment.

The pH value is one of the most commonly used water quality testing indicators, and the pH value of natural water is mostly in the range of 6-9. The pH value of drinking water should be between 6.5 and 8.5. The pH value of some industrial water should be guaranteed to be between 7.0 and 8.5, otherwise it will have a corrosive effect on metal equipment and pipelines. pH value and acidity, alkalinity are both different and connected. The pH value indicates the strength of the acidity and alkalinity of the water, and the acidity or alkalinity is the content of acid or alkali substances in the water. The change of pH in water quality indicates the degree of water pollution.

If the water pH is too high or too low, the aquatic organisms in it will die. PH value also affects the dissolved oxygen and toxicity of chemicals and heavy metals in the water. Most aquatic organisms like the pH range between 6.5 and 9.0, but some can live in water bodies with a pH beyond this range.

Therefore, whether it is industrial production, aquaculture, sewage treatment or agricultural production, a ph sensor is needed to detect the ph value in the liquid, which requires us to choose the appropriate ph sensor.

What does a pH sensor consist of?

A typical pH sensor (usually a glass electrode) consists of:
Measuring electrode: Contains a special pH-sensitive glass that reacts with hydrogen ions in the solution.
Reference electrode: Provides a stable voltage for comparison.
Internal buffer solution: Usually a pH 7 solution sealed inside the sensor.
Temperature sensor (in modern sensors): Helps adjust readings because pH can vary with temperature.

What is temperature compensation in pH sensors?

Temperature compensation corrects pH readings to account for temperature-related changes in electrode response.
Most modern pH sensors include:
Automatic Temperature Compensation (ATC)
Built-in temperature sensors
This feature improves accuracy, especially in environments where water temperature fluctuates.

What are the advantages of our pH sensor?
