Product description
Aqua Master Calibration Solution pH 4.01 100ml: product details and use
The Aqua Master Calibration Solution pH 4.01 was developed specifically for the accurate calibration of digital pH meters. Regular calibration is crucial for consistently accurate pH readings – especially when monitoring nutrient solutions in growing.
With its precisely defined reference value of pH 4.01, this solution is ideal as a calibration point in the acidic range and works perfectly with pH 7.00 for 2-point calibration.
Why is pH calibration so important?
pH has a major influence on nutrient availability. Even small deviations can mean plants can no longer absorb important minerals properly.
Regular calibration with the Aqua Master calibration solution ensures that your meter:
Delivers precise, stable readings
Minimises measuring errors
Works reliably
Guarantees accurate results in the long term
Easy to use
Using it is straightforward:
Pour a small amount of the solution into a clean container
Immerse the pH probe
Calibrate the meter according to the manufacturer's instructions
For the best results, rinse the electrode with distilled water before and after calibration. The solution is ready to use straight away.
