3 Complete Kit
4 Preparation Before Use
4.1 Things needed in addition to what’s in the box: A cup of distilled water (8-16oz) for
rinsing the probe, and clean tissue paper for removing excess water.
4.2 For PH60 and PH60F: If the tester hasn’t been used for a long time (> 1 month), or
the tester’s response is very slow, you can soak the probe in the 3M KCL storage
solution overnight before use to restore the electrode’s sensitivity. The storage
solution is 3M KCL (SKU: AI1107). One bottle of 10mL storage solution comes with
the tester kit. If the storage solution was contaminated, please replace with new ones
timely. *DO NOT use any other brand’s storage solutions as potential damage could
be caused to the probe.
4.3 For PH60S: NEVER store the spear pH probe in a dry condition because permanent
damage can be caused. The spear probe should always be stored in the 3M KCL
soaking solution when not in use.
