The Aqua Master EC calibration fluid 12,88 is a solution for calibrating and adjusting household and garden EC meters (conductivity meters). Regular cleaning and continuous maintenance maximize the life and accuracy of EC meters - this fluid provides complete assistance in this. It is recommended to clean EC meters every 30 days. The calibration fluid should be stored between 15-25°C. The EC calibration solution is required for EC measuring instruments.

Usage
The meters are usually calibrated by the manufacturers at the factory, but the factory setting can change over time. Therefore, the instrument must be calibrated before measurements. To do this, a calibration solution must be used. To begin with, it is worth rinsing the instrument's electrode with salt-free RO water. After that, the EC value of the liquid can be measured, so the accuracy of the instrument will be visible. If the deviation value is greater than the accuracy of the instrument, calibration is necessary. After calibration, the instrument will measure more accurately, a deviation of 1-2% is acceptable. This solution can also be used for TDS meters.
