pH Buffer Solution 4.00 - 300ml

Calibration fluid for pH meter 4.00 (300ml)

The maintenance and regular calibration of a pH meter is certainly not a superfluous expense. After all, with a pH meter you test the exact pH value of your irrigation water, which plays a role in the effective absorption of nutrients, microelements and minerals that should not be underestimated. Most manufacturers of pH meters therefore recommend recalibrating or checking the meter every month. The packaging contains a conversion table for calibrating pH meters without temperature compensation.
