Understanding How ORP probe Is Used in water-quality testing

You may have heard of the ORP probe, but what does it mean? What role does it play? It is an important device used in water-quality testing! ORP probe measures & indicates the degree of oxidation or reduction of a substance in water or any liquid. The ORP probe measures the purity of the water and its capacity to remove impurities.

What Is Oxidation Reduction Potential (ORP)?

An indicator of a substance's capacity to either oxidize or reduce another substance is its "oxidation-reduction potential," or ORP. In an aqueous solution, it gauges the activity of the oxidizers and reducers. It is a potentiometric measurement from a two-electrode system, and it is quite similar to a pH sensor. An ORP meter with a positive reading indicates that the liquid material is an oxidizing agent!! Unlike a pH sensor, an ORP probe sensor measures the ratio of oxidized to reduced forms of all chemical species in the solution. If the result is negative, the material is a reducing agent. The good thing is that it is easier to apply with the knowledge we have today. Get the right ORP probe sensor and test it today!

The Importance of ORP Readings in Water Testing?

There are various reasons why someone might be curious to know a substance's ORP. ORP is a crucial component of water testing. It is used to determine the oxidation and reduction properties of the water & how clean or contaminated it is. Proper ORP (Oxidation-Reduction Potential) measuring and understanding its limitations is important. It will be helpful to minimize the potential for increased corrosion rates, excessive chemical feeds, and biofouling. All of the agents that are present in a material have an impact on its ORP. Only bases and acids (hydrogen ions) are recognized by pH reading (hydroxide ions). Hence an Oxidation reduction potential measurement is considered more informative than a pH reading alone. Hence, the ORP probe sensor is helpful in knowing things!

There are various types of base ions and dissolved oxygen in natural water bodies. When certain industrial wastewater is released into the water, a lot of ions and organic matter are present. When you add chlorine to the water, the chlorine gives up its electron surplus to neutralize or oxidize potentially harmful bacteria. By raising the water's ORP level, active chlorine electrons neutralize pollutants. As time goes on, chlorine degrades and loses its ability to oxidize. The water's total ORP rating eventually drops. Although the ratio of disinfectant in the water and ORP levels often correlate, ORP evaluates the net oxidation and reduction characteristics of all agents in the environment.

Common Uses for ORP probe sensor

ORP probe sensor is an essential tool in a wide variety of industries and applications. The most common application of the ORP probe sensor is in swimming pools. It tests the water-quality chlorinated swimming pools. In addition to checking the water quality in chlorinated swimming pools, it is used in the water treatment and food processing industries. It guarantees that water is safe to recycle or drink and is free of pollutants. A positive ORP value will be present in bottled water or clean tap water.

When should I replace my ORP probe?

The replacement of the ORP probe sensor is based on how frequently you use it. It is also based on the temperature and type of sample you are measuring, and the care and maintenance of the probe. Most people get a good result for at least 12-18 months out of an ORP probe. After that they may need to replace it. 

Conclusion

The ORP probe sensor is integral to water testing. It shows the oxidation and reduction characteristics of clean or contaminated water. Water treated with a sanitizing agent has a higher oxidation potential. It will produce a higher ORP reading. Routine monitoring of the ORP probe sensor ensures the effectiveness of a sanitizing agent in water. Based on it you can adjust your water treatment plan.
