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. • Find more tips and tricks for pH measurements on our blog: • FAQ: All about pH calibration: https://www.metrohm.com/en/discover/b... • Avoiding the most common mistakes in pH measurement: https://www.metrohm.com/en/discover/b... • 0:00 Introduction • 0:27 Calibration frequency • 1:07 Material needed for calibration • 1:45 Preparations for the calibration • 2:22 Settings on the meter • 2:38 How many buffers should you use • 2:55 Selection of buffer type • 3:03 Start calibration • 3:36: Effect of temperature on calibration • 3:55 Continuation of calibration • 5:08 After the calibration
