Significance of Measuring Boiler Water Hardness and Introduction to FT-GL02 Water Hardness Meter

Industrial boilers are devices used to heat water into steam, which can be employed to drive turbines for power generation, provide heat sources for production workshops, and so on. If the hardness of boiler water is high, calcium and magnesium ions in the water will form scale on the heating surface of the boiler. This will lead to a reduction in heat transfer efficiency, an increase in boiler fuel consumption, and may also cause local overheating, even serious safety accidents such as boiler tube bursting. It will also aggravate the corrosion of the boiler and shorten its service life. Therefore, measuring the hardness of industrial boiler water is conducive to ensuring the safe operation of the boiler, reducing energy consumption, and prolonging the service life of the equipment.

The main measurement methods for water quality hardness include colorimetry, titration, and ion-selective electrode method. The colorimetry method involves adding a specific color-developing agent to the water sample. The color-developing agent reacts with calcium and magnesium ions in the water to form a colored compound. Then, a spectrophotometer is used to measure its absorbance, and the hardness value of the water sample is determined according to the corresponding relationship between the absorbance and the hardness concentration. The titration method uses complexometric titrants such as EDTA to carry out complexation reactions with calcium and magnesium ions in the water. The titration end point is determined through the abrupt change of the indicator's color, so as to calculate the hardness of the water sample. The ion-selective electrode method uses electrodes that have a selective response to calcium and magnesium ions to measure the potential change of the electrodes in the water sample and calculate the hardness of the water sample.

The FT - GL02 Water Hardness Meter is an instrument capable of online monitoring of total water hardness and chloride ions. It integrates water hardness sensors, chloride ion sensors, and measurement module communication storage, and can quickly and accurately record key parameters in water bodies.

Here are its advantages:
