Special water treatment agents often contain fluorescent substances that detect leaks in the water circuit and also serve as an aid for the correct dosing of water care agents. This also ensures corrosion protection. To ensure maximum accuracy of results, the meter must be calibrated with the fluorescein standard. It verifies calibration accuracy to ensure that the meter is functioning properly.
