Digital pH Meter for Hydroponics

Check nutrient-solution pH before making an adjustment.

This handheld digital pH meter provides a direct way to check acidity or alkalinity in water and nutrient solution. Its pen-style body has a digital display, power control, calibration control and protective probe cap. Use it as part of a regular reservoir-checking routine, alongside a separate conductivity or TDS measurement when you need nutrient-strength information. Rinse the probe between samples, use suitable calibration solutions and follow the supplied storage instructions. A pH reading answers one question about the sample; it does not identify individual nutrients or prove that water is safe to drink.
