2. **pH Meters**: For more accuracy, pH meters are widely used. These electronic devices consist of a glass electrode that can measure the hydrogen ion concentration in a solution. When immersed in a solution, the glass electrode generates a voltage that is converted into a pH reading. Modern pH meters can provide quick and precise results, making them suitable for various professional applications.

3. **pH Probes**: Similar to pH meters, probes can measure pH levels in specific environments such as soil or water bodies. They are designed for rugged conditions and can provide continuous pH data, which is particularly useful for environmental monitoring.

4. **Titration Method**: Another classic laboratory technique, titration involves adding a reagent of known concentration to a solution until a reaction reaches neutralization (indicated by a pH indicator). This method can provide very accurate pH measurements, but it typically requires more time and expertise compared to electronic methods.

5. **Colorimetric Methods**: These involve adding a pH indicator dye to a solution that changes color according to its pH level. Colorimetric methods are often used in educational settings or initial screenings for pH. Modern techniques can utilize colorimeters to provide more precise readings.

While measuring pH, it's essential to consider factors such as temperature, as pH can vary with changing temperatures. Calibration against a known standard is crucial for maintaining accuracy, and this is where standards like the 49 Jili pH come into play, ensuring consistency and reliability across measurements.
