Vitalink - pH Test Kit (Wide Spectrum)

A quick colour check on your feed's pH, no batteries needed

The VitaLink pH Test Kit (Wide Spectrum) is a colour-change indicator test for checking nutrient solution pH in hydroponics, coco and soil. Add a few drops, compare against the chart and read the pH within seconds - ideal for routine checks and a dependable backup when a digital meter drifts, needs calibrating or fails, since incorrect pH is one of the most common causes of nutrient lockout indoors.

Key Benefits

• Wide pH 4.0 to 8.5 range in 0.5 increments
• Colour-comparison reading in seconds
• No batteries or calibration to worry about
• Reliable backup when a digital pH meter fails or needs recalibrating
• Works across hydro, coco and soil indoor setups

Catch pH drift before it locks out your feed

When pH drifts outside the ideal band, plants struggle to take up nutrients, leading to nutrient lockout, slow vegetative growth and weak root development. A quick regular test lets you spot and correct drift before deficiencies show, and keeps you covered when electronic meters are down.

How to Use

1. Fill the supplied vial with a small sample of your nutrient solution.
2. Add a few drops of the VitaLink pH Test Indicator reagent.
3. Gently shake or swirl the vial to mix.
4. Compare the resulting colour against the provided chart.
5. Match to the closest value to read pH between 4.0 and 8.5, then adjust with pH Up or Down as needed and re-test.
