pH Indicator Strips – these strips are used to measure the pH of an indigo vat to determine if more alkali or acid is needed to balance the vat. They may also be used 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. Since natural dyes colors may be shifted by adjusting the pH of the dye bath, our pH strips come in handy when deciding on increasing or decreasing pH.
- Packaged in sets of 50 strips with a full color indicator chart and instructions for use.
