Why monitor the pH of water?

pH measurement is a key step in many water testing and purification processes:

● A change in the pH level of water can alter the behavior of chemicals in the water.

● pH affects product quality and consumer safety. Changes in pH can alter flavor, color, shelf-life, product stability and acidity.

● Inadequate pH of tap water can cause corrosion in the distribution system and can allow harmful heavy metals to leach out.

● Managing industrial water pH environments helps prevent corrosion and damage to equipment.

● In natural environments, pH can affect plants and animals.

How to calibration the pH sensor?

The majority of meters, controllers, and other types of instrumentation will make this process easy. The typical calibration procedure consists of the following steps:

1. Vigorously stir the electrode in a rinse solution.

2. Shake the electrode with a snap action to remove residual drops of solution.

3. Vigorously stir the electrode in the buffer or sample and allow the reading to stabilize.

4. Take the reading and record known pH value of the solution standard.

5. Repeat for as many points as desired.
