overview:
This method is a simple and rapid way to determine the hardness of water quality. By testing the liquid, the hardness of the water source can be quickly measured to determine whether it meets the standard. If the water hardness does not meet the standard, further testing of the water hardness can be conducted.
operating steps
Generally, only hardness reagent solution is needed. Take a certain amount of water sample, add hardness reagent solution to make it react, and then observe the color change of the water sample to determine the hardness of the water based on the color change.
Applicable scenariosCan be used for preliminary testing of water hardness in households, schools, small businesses, etc., such as testing domestic water, boiler water, etc.
pros and consEasy to operate, does not require professional technicians, and can obtain results in a short period of time. However, the detection range and accuracy are limited, and there may be differences in the detection effect of different brands and models of reagent kits.
