How to calibrate your pH electrode

In this video, we show you how to calibrate a pH electrode on a 913 pH/DO Meter or 914 pH/Conductometer. Calibration of your pH electrodes is essential for accurate pH measurements.

You will learn:
– how often you should calibrate your electrode,
– which material you need for the calibration,
– how to set the parameters for the calibration on the meter,
– how many buffers you should use,
– and why you need to measure the temperature during calibration.
