                    pH meter for the pool Checklist: These features are important in the test

                    • Test type: There are different methods for measuring the chlorine and pH value of the pool water.
                      • Test strips: Test strips are easy to use, but they are not 100% accurate. However, the strips are considerably cheaper to purchase than other measuring devices. For the measurement, the strip is simply held in the water and the chlorine and pH values are read from it.
                      • Test kit with tablets: Test kits with tablets are inexpensive to buy and accurate to measure, making them a highly recommended type of measurement. A water sample must be taken for the measurement, the tablet is placed in the sample and the pH and chlorine value can be read from the coloration.
                      • Test kit with liquid: Test kits with liquid are also quite inexpensive and accurate. A water sample must also be taken here.
                      • Digital measuring device: Measurement with the digital measuring device is the most accurate type of measurement and a good choice for larger pools in particular. The digital measuring devices are more expensive than other methods, but the simple and accurate measurement makes the device worthwhile, especially if frequent measurements are carried out.
                    • Accuracy: The different pool water testers have different measuring accuracies. Test strips are the least accurate and digital meters are the most accurate. Test kits are also very accurate when used correctly.
                    • Measurements: Some measuring devices not only measure the pH value and chlorine content, but also bromine, alkalinity and water hardness, for example. These measurements can provide further information about the water quality.
                    • Calibration: Some models of pH meters have so-called calibration solutions, which are responsible for the accuracy of the results. It is recommended to calibrate the device regularly in order to obtain reliable pH values.
                    • Handling: Simple operation and a clear display enable the user to use the device without any problems. An illuminated display with large digits makes it easier to read values and helps to carry out measurements in poor lighting conditions.

                    FAQ: Frequently asked questions and answers

                    How do pool water testers work?

                    Test strips or test kits can be analyzed based on the discoloration of the strip or the water sample. There is always a color scale on the test cassette of the test kits for comparison, usually from yellow to red and white to pink. Electronic measurements indicate the value digitally and thus take away the task of comparison.

                    What pH meters are available for the pool?

                    There are test strips, test kits and digital pool testers to measure the pH value. The measuring devices can also be used for aquariums and swimming pools.

                    Which pH meter is best for the pool?

                    Digital measuring devices such as the PoolLab from Powerhaus24 are the most accurate. However, which measurement method is the best depends on your own needs. If you only want to check once whether the pool water is in the pH-neutral range, you are also well advised to use inexpensive test strips.

                    Where can I buy pool water testers for the pool?

                    A large selection of different pool water testers are offered on online stores such as Amazon. The reviews of other buyers are particularly helpful here, as they provide valuable practical information about the products.

                    How much do good pool water testers cost?

                    Pool water testers cost between approx. 10 and 130 $.

                    Which pool measuring device is the test winner?

                    Most online tests recommend digital meters, but there is no independent test on pool water testers yet.

                    How high should the pH value in the pool be?

                    A pH value serves as an indicator of the acidity and alkalinity of the water. The ideal pH values for pool water are between 7.0 and 7.6. These values are pleasant for the skin and eyes of pool users.

                    How reliable are pH meters?

                    The reliability of a pH meter depends on the quality of the respective model. As a rule, expensive measuring devices are accurate, reliable and user-friendly. When looking for a suitable model, it is recommended to reach for a device that is pre-calibrated. If the device is used regularly or not used at all, it should be recalibrated regularly in order to obtain accurate measurement data.

                    What alternatives are there to pH meters?

                    Anyone who attaches great importance to clean and pleasant water in the pool should definitely pay attention to chlorine pills. They remove bacteria and prevent algae growth in the pool.

                    How is a pH meter cleaned?

                    To extend the service life of a pH meter for the pool, it should be maintained. Thanks to regular rinsing with clear water, soiling is removed from the surface. If mold has formed on the appliance, it is recommended to clean the appliance with a mixture of water and vinegar or with a thin ethanol or acetone solution.
