Milwaukee MA9112 pH 12.45 Calibration Solution

The MA9112 is a lab grade pH 12.45 buffer solution certified to meet the standard to an accuracy of ±0.01 pH.  It removes inaccuracies involved with mixing buffers and is important for the correct use of electrodes and obtaining the most accurate and reproducible readings. 

Probe calibration is a simple procedure.  For optimal performance it should be done any time readings become suspect or at least once a month.  Simply open the solution, pour into a beaker or container, and insert the tester or electrode to start the calibration process.

The solution is sealed with an airtight, tamper proof cap.
