pH calibration solutions are often called buffer solutions. Most meters need at least 1, usually pH 7 buffer. You may need a pH 4 or 10 depending on the range of pH values you will be measuring. HANNA buffer solutions are prepared according to precise formulas and are standardized with a
HANNA®’ buffer solutions are prepared according to precise formulas and are standardized with a pH meter calibrated according to the NIST standards. The 20 mL sachets are single-dose whereas, for more demanding applications. All pH 7 solutions show batch number, expiration date and the correlation table between pH and temperature.

The 20 mL sachets are single-dose whereas, for more demanding applications. All pH 4 solutions show batch number, expiration date and the correlation table between pH and temperature.
The 1413 µS/cm calibration solution is best suited for general use. This solution is also available in combined kits with HANNA pH 7 buffer for easy calibration of multi-parameter instruments.
To minimize clogging and ensure fast response time, always keep the glass bulb and the junction of your pH electrode moist. Store the electrode with a few drops of HI 70300 storage or pH 7 buffer solution in the protective cap.
HANNA is one of the few producers to offer calibration solutions in packages from 20 to 500 mL for lab and field applications. Its packaging has been designed to keep air and light from damaging the solution. Use Hanna conductivity solution to ensure your TDS meter is reading properly.
