GIB/Watermaster pH Buffer 7 300ml

It is important that the probe on your pH Meter does not dry out as this could damage the probe and give you incorrect pH readings.

The pH probe should be stored in KCL-PRO storage solution whenever it is not being used ! This will maximise accuracy and prolong the life of the electrode. It is as simple as adding a few drops to your pH Meter cap and closing it ! This liquid is ideal for storage of all pH probes. The probe should be topped up regularly to maintain correct levels. Not for refilling gel based electrodes.
