VitaLink – pH Test Kit
£5.00
These cost-effective and easy-to-use pH test indicators give a quick reading of the pH of your nutrient solution.
The VitaLink ESSENTIALS pH Test Indicator – Narrow Spectrum, and VitaLink ESSENTIALS pH Test Indicator – Wide Spectrum, change 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.

Growth Technology – pH Probe Refill & Storage – 300ml
pH Probe Refill & Storage Solution
This solution can be used to store pH meters when not in use.
Basically, the probe glass bulb at the end of the meter should be just immersed in the solution. This will condition the probe and maximise its useful life.
The same solution can be used for refilling the probes on certain meters.
