Chemical monitoring is a way of measuring or maintaining the quality of a fluid in any given container. It is a type of fluid control system that generally focuses on monitoring the pH levels of that fluid, determining whether it is too acid or alkali for its function.What is chemical monitoring used for?Chemical monitoring is broadly used to detect appropriate chemical levels in a fluid. Often this fluid is water. For example, chlorine levels are routinely tested in swimming pools using a chemical monitoring device.In industrial settings, chemical monitoring is used as part of the fermenting process and in maintaining the correct chemical levels for dying fabrics.Types of chemical monitoringThere are two main methods of chemical monitoring:Using a sensor or a probe to monitor the level of a given chemical in a fluid. If the level goes below or above the appropriate range, the pH will have to be manually adjusted.Using a buffer solution to keep the chemical levels of the fluid at the appropriate pH. Buffer solutions are very resistant to change from acid or base.
