Straight Talk About Selecting pH Sensor
Let’s face it: replacing pH sensors on a regular basis is expensive, and in many circumstances, the frequency can be considerably reduced by selecting the correct sensor. Too often, users simply replace a pH sensor with the identical type, without knowing why the pH sensors are failing.
When choosing a pH sensor, various things must be considered to ensure the sensor’s durability and longevity:
Materials: The pH sensor’s construction materials should be able to endure the extreme circumstances of the application. If the sensor is going to be used in a corrosive environment, for example, it should be built of a corrosion-resistant material like stainless steel or titanium.
The pH sensor’s structure should be sturdy and lasting, with well-sealed joints and strong electrical connections. This will aid in the prevention of leaks and will ensure that the sensor can endure hard handling or exposure to harsh environments.
Calibration: Proper pH sensor calibration is crucial for guaranteeing accuracy and longevity. To guarantee that the sensor is delivering reliable readings, it should be calibrated on a regular basis with a high-quality pH reference solution.
Regular maintenance of the pH sensor is required to ensure its accuracy and lifespan. Cleaning and drying the sensor after use, replacing the reference electrolyte as needed, and inspecting the electrical connections for signs of corrosion or damage are all examples.
Compatibility: The pH sensor should be compatible with your facility’s process control and data management systems. It should have simple communication interfaces and work with a variety of process control and data management tools.
When choosing a pH sensor, the price of the sensor should be taken into account. While investing in a high-quality sensor is crucial, the cost of the sensor should be evaluated against its estimated lifespan and total return on investment.
Overall, it is critical to evaluate all of these variables when selecting a pH sensor to ensure that the sensor is long-lasting, accurate, and appropriate with the needs of your facility.
