VitaLink Essentials pH Test Indicator Narrow Spectrum Test Kit from 5.6 - 7.4

Cost-effective and easy-to-use pH test indicator to give a quick reading of the pH of your nutrient solution.

The VitaLink ESSENTIALS narrow Spectrum pH Test Indicator changes colour in response to different pH values. 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.

The VitaLink ESSENTIALS pH Test Indicator – Wide Spectrum measures between 5.6 and 7.4 in increments of 0.2.
