5 Things to Know Before Use
1)
Be careful about the glass tip of the probe. It can break if being contacted by external force. If
broken, the probe needs to be replaced.
2)
Things needed in addition to what’s in the box:
a)
Distilled or deionized water (8-16oz) for rinsing the probe after each test
b)
Tissue paper for drying the probe
3)
For PH60-Z and PH60F-Z testers:
a)
A few drops of water are added to the probe cap to keep the pH electrode in an activated
state before the tester leaves factory. Generally, users can start using the tester directly. If
the measuring response is slow, users can soak the pH electrode for 30 minutes in the 3M
KCL storage solution (fill to the fill-line) before using it; if the electrode is dry for a long
time (> 1 month), the pH electrode responds slowly, You can soak the pH electrode for 8
hours in the storage solution before using.
b)
When the tester is not in use, we recommend adding one to two drops of tap water to the
probe cap, and close the cap (be careful not to add too much water). This way, the pH
probe’s sensitivity can be maintained and users can start using the tester right away next
time.
c)
Do not soak the pH electrode in purified (e.g. distilled/deionized) water for a long time, which
will make the electrode response slow. If this happens, soak the pH electrode in 3M KCl
solution for 3~5 hours, and then re-calibrate it before using.
d)
The storage solution is 3M KCL (SKU: AI1107), and the tester kit comes with a bottle of
10mL storage solution (can be used repeatedly). If it is contaminated, replace it with a new
one. Please do not use other brands’ storage solutions as they may contain other chemicals
that can cause damage to the electrodes.
4)
For PH60S-Z Spear pH Tester:
◼
NEVER
store the spear probe in a dry condition because permanent damage
CAN
be
caused. The spear probe should always be stored in the 3M KCL soaking solution.
