We all enjoy taking a bath in a tub or pool as it is relaxing and fun but many forget how important it is to conserve the water’s good condition. To achieve this last step, one of the things that should be done more regularly is the measurement of the pH and chlorine levels it has. These elements play a role in water maintenance because they are key when selecting the type of chemical that will be applied in it; they are also directly related to aspects associated to the health of the skin and eyes of people.
Regardless of whether there is talk of a pool for several people, an individual bath tub or a hot tub for two people; taking control of the compounds in their water is something that may not be overlooked. The pH is a measure that indicates the degree of acidity or alkalinity of certain solutions, and chlorine, on the other hand, it is a chemical element generally used for the disinfection of aqueous solutions, both, according to the level in which they are, represent and indicate its salubrity’s rating.
The PH measurement is established on a scale from 0 to 14, so that the assessments closer to 0 indicate higher acidity and those closest to 14 indicate higher alkalinity, with 7 being the neutral point or ideal PH. Therefore, for water to be adequate when it is used, this level must be kept between 6 and 7. The meters, in this case, are divided into two groups: those that consist of electronic devices to perform their work and those constituted by technologies that work based on direct chemical reactions.
Both methods use chemical reagents to make an analysis of each element to be measured. However, the former, also known as OTO meters, are composed of panels or indicators that show the levels of total chlorine and PH by performing tests in which a few drops of the reactive compound are added to a specific amount of the liquid and, in this way, the reaction it exerts upon contact with water is studied. These devices work with changing shades, which reveals, according to the color of the sample, the information of the phase in which it is located.
In the second case, the most common choice is the use of tablets. Also known as DPD meters, they allow detecting the amount of residual free chlorine and pH in water through a simple test, these also have a colorimetric scale that serves to compare the color of the water stained after adding the reagent. When working with tonalities, a wrong perception can be obtained if the process is executed in a place with light problems, for this reason it is recommended to perform it in spaces that do not have intense or sparse light and that contrast the results with a white surface in the background.
It should be noted that the levels of both elements are modifiable, that is, they can be altered to make them higher or lower and thus achieve the desired degree of each one. Also, there are corrective meters whose task is, in addition to obtaining the information on the state of the chlorine and pH of the water, to correct it automatically balancing the mismatched levels of each component.
Remember that, in addition to keeping water compounds in good condition, the use of a good filter and pump for hot tubs or pools is essential to keep the water clean. Furthermore, the use of chemicals for its purification and disinfection can be affected by PH and chlorine levels, since these directly influence the reaction that artificial substances can generate when they come into contact with water and its components.
