Notes on ph meter digital
Pay attention to the storage of the PH electrode. It is better to cover the glass probe with a plastic sleeve filled with 3mol/L potassium chloride solution.
Do not touch the glass film on the glass bulb with hard objects, it is extremely thin and fragile.
When using for the first time, in order to avoid affecting the measurement accuracy due to drying, the electrode should be immersed in a 3mol/L potassium chloride solution for about 2 hours.
Usually if you need to use the ph meter digital continuously, it is recommended to calibrate it every 24 hours;
In order to make the measurement data more stable, it is necessary to keep the lead wire of the electrode in a static state during measurement.
