    ชุดทดสอบน้ำในอุตสาหกรรมเหมืองแร่ (แอซิดิตี้,อัลคาลินิตี้,เหล็ก,pH)

    HI 3819

    Acid Mining

    The acid mining industry produces discharge water which can be both acidic and alkaline, depending on the metal type. The discharge water can also contain metals such as iron. Since the run-off water will eventually find its way to lakes and rivers, it is important to test it to make sure it does not pollute the environment and water reservoirs.

    HANNA®‘ combination test kit HI 3819 includes all the necessary tests for alkalinity, acidity, pH and iron. The reagent bottles are in easy-to-recognize ascending numbers, and allow your tests to be more expedient and less time consuming.

    The testing procedures are clearly shown in the step-by-step instruction manual so that anyone can carry out the analysis. For pH measurements use our electronic tester, pHep, to get faster and more accurate results than conventional litmus paper.

    The kit has all the necessary equipment to perform over 100 tests of acidity and alkalinity and 50 tests of iron.

    You can conveniently replace reagents separately as they run out (see Reagents). The number of pH tests has no limitations other than the life of the instrument itself.
