Solutions

To ensure accurate measurement results, pH and conductivity meters must be calibrated regularly. Calibration solutions (also known as buffer solutions) ensure that the meter displays correct readings. Apera recommends calibrating the meter before each important series of measurements.

pH buffer solutions:
– pH 4.01: Acidic reference value. Used to set the lower calibration point.
– pH 7.00: Neutral reference value. Standard for 1-point calibration and as the midpoint in 2-point calibration.
– pH 10.01: Basic reference value. Recommended when measurements in the alkaline range (above pH 8) are relevant.

Conductivity calibration solutions:
– 1413 µS/cm: Standard for drinking water and hydroponics applications.
– 12.88 mS/cm: For measurements in the higher concentration range.

Electrode Storage Solution:
The 3M KCl storage solution keeps pH electrodes moist and significantly extends their service life.

Tip: The CalBox set includes buffer solutions and a storage solution in a convenient carrying case, making it ideal for regular use.
