- PH liquid 4.01 zur Kalibrierung elektronischer pH-Meter
- Kalibriertabelle auf der Verpackung
Adwa liquid pH 4.01 for the calibration of the pH meters is used to adjust them to the valid values with these solutions. After calibration, discard the used solution. Do NOT pour it back into the bottle, as this may contaminate the whole bottle and make the solution inaccurate.
Adwa’s solutions are made from established formulas and standardized with a pH meter calibrated with NIST standard calibration stocks. Careful handling and a good cleaning are essential for good measurement results.
Adwa offers a wide range of calibration, maintenance, and cleaning solutions.
Note: It is essential to calibrate the pH meter periodically, and we recommend calibrating the pH meter once every one or two months, depending on the usage.
