These cost-effective and easy-to-use pH test indicators give a quick reading of the pH of your nutrient solution and contain 30ml of test solution.
The VitaLink ESSENTIALS pH Test Indicator – Narrow Spectrum measures between pH 5.6 and 7.4 in increments of 0.2 and will change colour in response to different pH values.
Use
Fill the supplied plastic vial with a small amount of your nutrient solution and add a few drops of the pH test Indicator reagent. Compare the resulting colour to the chart provided and read the estimated pH. Although not as accurate as using a pH meter to analyse your nutrient solution, this indication kit is a quick, precise and cost-efficient measure, giving over 100 readings. It is also ideal as a backup solution in the case your pH meter should stop working.
