The Calibration Solution Set provides precise and reliable calibration for pH and conductivity meters. It includes two pH calibration solutions (pH 4.01, pH 7.00), two EC calibration solutions (1.413 mS, 12.88 mS), and a 3M KCl storage solution, each in a 250ml bottle. The set also comes with a Calbox, allowing easy organization and storage of up to four different solutions, making calibration more convenient.

The pH calibration solutions offer an accuracy of ±0.015 pH for precise measurements. They are color-coded for quick identification—pH 4.01 (red) and pH 7.00 (green). The EC calibration solutions are compatible with all types of conductivity meters. The 3M KCl storage solution preserves the sensitivity and accuracy of pH/ORP electrodes, ensuring long-term performance.

Ready to use immediately, these solutions eliminate the need for mixing powders with distilled water. With a long shelf life and batch certificates available online, this kit is ideal for both laboratory and field applications.
