Phydrion Pencil pH Indicators

    SKU: TEC006001





    The Hydrion Mechanical pH Pencil measures the pH of any surface to the nearest full pH value.  The Hydrion pH pencil can be used to test irregular or uneven surfaces, and is also effective on porous materials and impervious solids.  It offers clear bright single color matches at every 1.0 interval from pH 0.0-13.0.

    Tests are conducted by using distilled water on the surface to be tested, make a mark with the pencil, and wait a few minutes until color stabilizes and match to chart.   

    Pencils test within full pH range of 0 - 13. Box contains 3 pH pencils.
