Large range online ORP probe sensor for pool

The measurement principle of the ORP Probe is based on the potential change of the redox reaction. The ORP electrode usually consists of a reference electrode and a working electrode. When a redox reaction occurs, the reference electrode provides a stable potential as a reference, and the working electrode is in contact with the solution to be measured. In a redox reaction, electrons are transferred between the oxidant and the reducing agent in the solution, resulting in a change in potential. ORP measuring electrodes can be made of a variety of metals, such as nickel, copper, silver, iridium, platinum, gold, etc. After testing, platinum and gold have higher ORP values and higher measurement sensitivity. Compared with other ORP electrodes, the redox potential of platinum and gold in their ion equilibrium activities is extremely low, so they have little impact on ORP measurements. Daruifuno's ASR401 online ORP probe uses ring-shaped platinum, with a wide measurement range and fast response. In addition to being used in municipal water treatment and industrial wastewater applications, ORP electrodes also play an important role in swimming pool water monitoring. The purpose of monitoring the ORP value in swimming pools is to evaluate the redox potential of the water body to determine the disinfectant concentration and disinfection effect in the water body. The ORP value can reflect the oxidation or reduction of water, so it can be used to monitor the concentration of disinfectants in water bodies, such as free chlorine or ozone.

Specification

What is the ORP value standard for swimming pool water?
The standard of ORP depends on the disinfectant used and the water quality requirements. Generally speaking, for swimming pools, the recommended ORP range is 650-750mV. Within this range, the concentration of disinfectant is high enough to kill bacteria and viruses, but without adversely affecting human health. However, specific ORP standards may vary depending on region, regulations and water quality requirements. Therefore, relevant local guidelines and regulations should be followed when monitoring and adjusting ORP values.

The ORP electrode can be used with our online ORP controller. The ORP electrode needs to be tested and calibrated regularly to ensure accurate readings. Usually the life of the ORP electrode is about 6-12 months. When you find that the readings are inaccurate, the electrode drifts too much, and the calibration is useless, consider replacing the electrode. We also provide APX2-PD, a dual-channel swimming pool dedicated controller that can connect two electrodes at the same time, pH or ORP electrodes, to monitor two water quality parameters at the same time and calculate the value of residual chlorine.
