Calibration solution pH 9.0 / 50ml
It is always best to calibrate the measuring instruments in the range in which the measurement is also carried out.
This means that an (additional) calibration with a value of 9.0 is very useful in seawater aquaria in the range of approx. 7.8 - 8.4.
Please note that the calibration solution 9.0 pH is more sensitive to soiling than in the case of PH 4.0 and 7.0.
Therefore NEVER place the electrode in the original bottle but ALWAYS fill an appropriate quantity from the original vial In a clean container.
This also applies to PH 4.0-7.0 and any other calibration solution.
