3. Complete Kit
Things needed in addition to what’s in the box
A clean cup, distilled water (8-16oz), and tissue papers for rinsing and drying the
probe.
n If you see some white crystalline solid leaked out of the pH probe, that’s the reference
solution (3M KCL) inside the probe. It is NOT a sign of any defective issue. It is a normal
phenomenon when the probe is stored dry for a period of time. It proves that the
junction of the probe is working well. Users can simply rinse the probe in distilled water
to remove the solids and use the tester as usual.
4. Calibration
4.1 If it’s first time use or the tester hasn’t been used for a long time, pour some
pH 4.00 solution to the Fill line in the probe cap, soak probe for about 15 minutes
to hydrate the pH sensor.
4.2 Short press to turn on. Rinse in distilled water; shake the meter in the
air and use tissue paper to dap off excess water.
