Application
Tips: How does the potassium sensor compensate for temperature variations?
The potassium sensor is equipped with automatic temperature compensation. This feature adjusts the readings based on temperature fluctuations, ensuring that the sensor maintains accurate and stable data regardless of temperature changes. Since temperature can significantly affect the ion concentration in water, automatic compensation helps eliminate this variable and enhances the reliability of the readings in environments where the water temperature may change frequently, such as in outdoor applications or in industrial environments where water is heated or cooled.
