Description
The VitaLink ESSENTIALS pH test indicator kit employs a universal indicator solution to alter the color of a small sample of your nutrient solution. By comparing this color to the spectrum chart, you can determine the pH level of your solution. While not as precise as utilizing a pH meter for analyzing your nutrient solution, this indicator kit provides a swift, accurate, and cost-effective method, offering over 100 readings.
The spectrum covers pH levels ranging from 4 to 8.5 in 0.5 increments.
