Electrodo de ph orp

pH and ORP are two important parameters in water quality monitoring. The pH value represents the negative logarithm of the activity of hydrogen ions in water and is an indicator for measuring the acidity and alkalinity of aqueous solutions. ORP, or redox potential, is a key parameter for measuring the redox reaction capacity in water bodies and reflects the relative strength between oxidants and reductants in water bodies. These two parameters are of great significance for assessing water quality health, ensuring drinking water safety, and guiding water treatment work. By monitoring pH and ORP values, we can fully understand the chemical state of the water body and assess whether the water quality meets relevant standards, thereby ensuring the safety and stability of the water quality. In the fields of ecological protection and research, aquaculture, etc., the monitoring of pH and ORP also plays an irreplaceable role, providing important data for relevant personnel to help them understand the health status and changing trends of water ecosystems and promote ecological protection work .

The core components of pH ORP electrode include glass ball, silver wire, reference electrode and electrolyte solution. Como elemento sensible del electrodo, la bola de vidrio reacciona específicamente con iones de hidrógeno (H+) en la solución para generar un potencial que es logarítmicamente proporcional a la concentración de iones de hidrógeno, que se usa para determinar el valor de pH de la solución. Como una ruta conductora, el cable de plata se suspende en la solución de cloruro de plata y forma una diferencia de potencial con el electrodo de referencia (generalmente compuesto de elementos de plata/cloruro de plata/AgCL). The potential difference is amplified by the measurement circuit to obtain the pH reading. Although the structure of ORP measurement electrode is different from that of pH electrode, its working principle is similar. It is made of various metals such as platinum and gold. It has an ionic lattice structure that promotes electron movement and can generate a potential difference. The ORP value and measurement sensitivity of platinum and gold electrodes are higher. Además, el electrodo PH ORP no solo se usa para el monitoreo de la calidad del agua, sino que también monitorea el cambio potencial en tiempo real en la titulación potenciométrica para determinar el punto final de la reacción química. También se puede utilizar como base del electrodo selectivo de iones para la medición selectiva de iones. Para garantizar el rendimiento y la vida útil del electrodo, se requieren cuidado y mantenimiento adecuados, incluido mantener la punta del electrodo húmeda, limpiarlo regularmente y almacenarlo en un entorno adecuado.
