5 Things to Know Before Use
1) A few drops of destilliertes water are added to the probe cap to keep the conductivity electrode in
an activated state before the tester leaves factory. Generally, users can start using the tester
directly. For conductivity electrode that hasn’t been used for a long time, users should soak the
electrode in 12.88 mS calibration solution for 5-10 minutes or in tap water for 1 to 2 hours before
use. Rinse the electrode in distlled/deionized water after each measurement.
2) The sensing rod of Model conductivity electrode is coated with platinum black to minimize
electrode polarization and expand measuring range. The platinum black coating adopted our
special processing technology, which improves the electrode performance and the firmness of
the coating. If the black sensing rods are stained, gently clean the electrode with a soft brush in
warm water containing detergent or alcohol.
3) 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
6 Conductivity Calibration
6.1 How to calibrate
1) Press key to switch to conductivity measurement mode (Cond). Rinse the probe in distilled
water and dry it.
2) Pour certain amount of 1413μS/cm and 12.88mS/cm conductivity calibration solution into
corresponding calibration bottles (to about half volume of the bottle).
3) Long press key to enter calibration mode, short press to go back to measurement mode.
4) Place the probe into 1413 μS/cm conductivity calibration solution, shake it for a few seconds and
allow it to stand still in the solution until a stable reading is reached. When stays on the LCD
screen, short press key to complete 1st calibration, the tester returns to measurement mode
