pH Indicator strips


In stock (can be backordered)



We use pH Indicator Strips to measure the pH of an indigo vat. In other words, they help us determine if we need more alkali or acid to balance the vat. We also use pH strips with Aquarelle Liquid dyes to measure the acidity of the dyebath.

These are extremely useful tools to quickly check your indigo vat or to determine the pH of your water supply. Natural dyes colors may be shifted by adjusting the pH of the dye bath. Therefore, our pH strips come in handy when deciding on increasing or decreasing pH.

  • We package our pH Indicator Strips in sets of 50 strips with a full color indicator chart and instructions for use.
