How to test water quality?Tests for limited budgets.

    Typical low-tech, portable, field test methods for chemical water quality monitoring fall into three categories:

    --Test strips.

    --Color disk kits.

    --Hand-held digital instruments.

    Test strips are the most convenient and ready-to-use method.


Need to check those indicators?

     UNICEF recommends prioritizing fluoride, arsenic, and nitrate for chemical monitoring.:


        --Fluoride


        --Arsenic


        --Nitrate


    Resources permitting:


        --Iron and Manganese


        --TDS


        --PH


        --Chlorine


    Other:


        --chloride


        --heavy metals


        --alkalinity or hardness


        --Test formats

    Typical low-tech, portable, field test methods for chemical water quality monitoring fall into three categories:


        (1)Color disk kits


        (2)Hand-held digital instruments


        (3)Test strips 


    Test strips are the most convenient and ready-to-use method:

    These are small, single-use strips that change color to indicate the concentration of a specific chemical. 

    Depending on the particular test, the user “activates” the paper or plastic strip by dipping it into the water sample and swishing it around, or by holding the strip in a stream of water. 

    After waiting for a short time, the user compares the test strip color with a color chart to read the concentration of the chemical. 


    Water quality test paper, how to use it:

        1: Put the test paper into the water for 2 seconds;


        2: Hold in the air for about 15 seconds;


        3: Compare the test strip with the map, which needs to be done within 60 seconds;


    The test is carried out at room temperature around 25°C.
