ชุดทดสอบน้ำสระว่ายน้ำ (pH 6.5-8.2)
114669 pH Test for swimming pools The pH determination using indicator solutions is suited for weakly buffered water samples. The pH value is measured semiquantitatively by visual comparison of the colour of the measurement solution with the colour fields of the colour card. Read More »

น้ำยาวัด pH (pH-indicator solution pH 9.0 – 13.0 )
109176 pH-indicator solution pH 9.0 – 13.0 When liquid pH indicators are used, the test solution should be colorless and clear, whenever possible. In the event the sample has any slight intrinsic color, test kits including a sliding comparator can be used to compensate for this intrinsic color. Read More »
