Hydrogarden VitaLink pH Narrow Spectrum Test Kit - EN/FR

These cost-effective and easy-to-use pH test indicators provide a quick reading of the pH level of your nutrient solution.

The VitaLink Essentials pH Test Indicator - narrow spectrum and the VitaLink Essentials pH Test Indicator - wide spectrum change color in response to different pH levels.

Fill the included plastic bottle with a small amount of your nutrient solution and add a few drops of the pH test indicator. Compare the resulting color with the provided chart to read the estimated pH value.

Although it is not as precise as using a pH meter to analyze your nutrient solution, this indicator kit offers a quick, accurate, and cost-efficient measure that provides over 100 readings. It is also ideal as a backup solution in case your pH meter stops working.

Available in narrow and wide spectrum in 30 ml bottles.

The VitaLink Essentials pH Test Indicator - narrow spectrum measures between pH 5.6 and 7.4 in increments of 0.2.
