Ideal pH Calibration Buffer Solution Kit：Includes 3 bottles 500 ml (16.9 fl oz) pH buffer calibration solution (pH 4.00, 7.00, and 10.01)，plus one bottle 30ml KCL pH electrode storage solution and 3 x 30ml measuring cups. Large-capacity design reduces the chance of running out mid-project and is suitable for long-term use in calibrating various pH meters
High Accuracy: The accuracy is ±0.05pH at 77.0℉/25.0℃. Ideal for professional and home calibration needs. Manufactured and tested under strict conditions using premium materials to ensure the accuracy and stability of the solutions
Extend Electrode Lifespan: The included pH electrode storage solution is essential for maintaining the pH probe in good condition—reducing electrode wear, enhancing measurement accuracy, and effectively extending its lifespan
Easy to Use: Ready to use upon opening, without the tedious dissolution process. Color coded for each pH buffer solution, easy to identification. Notes: The solution is valid for 1.5 years after opening, 3 years if unopened
Wide Applicability: This pH buffer calibration kit will be a good assistant calibrating various pH meters and pH testers, whether you’re using it for hydroponics, brewing, gardening, water treatment, food processing, laboratories or general testing
