Hydrion One Drop

Hydrion pH Indicator Solution kits feature specially formulated concentrated indicator solutions and give accurate pH measurements in very dilute test solutions with low buffer capacity (less than 0.1% phosphate buffer). Just one drop of the indicator solution added to 4 ml. of sample solution will provide an accurate ph reading, displayed in bright easy to view colors.

5-9 Hydrion pH Short Range Indicator Solution will give accurate pH readings at each .5 pH unit from pH 5.0-9.0, and is excellent for measuring the pH of waste water, pure water, tap water, rain water and pond water. Colors will remain stable for delayed readings.

The color chart has pH matches at [5.0][5.5][6.0][6.5][7.0][7.5][8.0][8.5][9.0]

Each kit is packed in a polypropylene protective case and contains one(1) polyethylene dropper bottle with 24 ml. of pH indicator solution, one(1) capped 4 ml. sample tube, and a laminated color chart.
