ESSENTIALS Lab

Item Description
These handy pH Test Kit Indicators give a quick reading of the pH levels in water & nutrients.
The VitaLink ESSENTIALS pH test indicator kit uses a solution known as universal indicator to change a small sample of your nutrient solution to a different colour. Compare this colour to the spectrum chart to indicate what pH your solution is reading at.
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.
The Wide Spectrum pH test indicator measures between 4.0 and 8.5 at increments of 0.5.
