pH Indicator Measuring Liquid pH4 to pH10

pH Indicator Measuring Liquid with Colour Scale to Measure the pH Value of Fluids and Water

• Ideal for alkaline water and other liquids.
• There is hardly a noticeable difference in colour between pH-9 to 10.
• You will notice an aftertaste at pH 9.5 in alkaline water, depending on composition of minerals in your tap water, it will be more or less noticeable.
• If it doesn't taste pleasant anymore, it is already over pH10 and if it is not drinkable anymore, it is close to pH11.
• The recommended maximum drinkable pH value is pH9.5, usually also the requirement for drinking water supply.
