Measurement Method:
Preparation: Before using the pH sensor, ensure the sensor is in good condition. If it is a glass electrode, check for damage and clean the electrode surface to ensure it is clean.
Calibration: The pH sensor must be calibrated before use. Typically, buffer solutions of pH 4.01, 7.00, and 10.01 are used for calibration. Immerse the electrode in these standard solutions and follow the device manual’s instructions for calibration.
Sample Measurement: Immerse the pH sensor into the water sample to be tested, ensuring the electrode is exposed to the water without interference from other substances.
Stabilization Time: The pH sensor requires time to stabilize. Wait a few minutes after immersing the electrode in the sample until the reading becomes stable.
Read the Measurement Value: Read the value displayed on the pH sensor screen or through the connected measuring device, and record the result.
Cleaning and Maintenance: After use, promptly remove the pH sensor from the water sample, rinse it, and wipe it with clean water. Perform regular maintenance, including cleaning and calibration, according to the device manual.
pH (PONDUS HYDROGENII)
pH, also known as hydrogen ion concentration index or acid-base value, is a scale of hydrogen ion activity in a solution, i.e., the usual measure of the acidity or alkalinity of a solution.
Under standard thermodynamic conditions, an aqueous solution with pH=7 is neutral, pH<7 is acidic, and pH>7 is alkaline.
In chemistry, pH historically stands for “potential of hydrogen” (or “power of hydrogen”), and is a scale used to specify the acidity or basicity of an aqueous solution.
Measuring method
A pH sensor is a device used to measure the acidity or alkalinity of a water body. The pH value indicates the degree of acidity or alkalinity of a solution and is an indicator describing the concentration of hydrogen ions in the solution. The pH sensor determines the pH value of the water body by measuring the potential of the electrode.
