How to Install the Electrode
1. Find the conductivity BNC socket (where it shows Cond) on the conductivity meter; Open the
rubber cap; Insert the BNC connector of the electrode to the BNC socket while twisting clockwise
until it’s locked.
2. After connecting the new electrode to your meter, adjust the meter’s constant K to 1.0 according
to the instruction of your meter’s manual. Then perform a 2 to 3-point calibration to ensure the
accuracy.
How to Use the Electrode
1. There is a proper amount of deionized water in the cap on top of the electrode. The conductivity
sensor is soaked in it to keep its sensitivity.
2. Before measuring, loosen the bottle cap, then pull out the electrode while twisting
counterclockwise. Place the storage bottle at a safe position.
3. Rinse the electrode with distilled or deionized water and blot-dry it with clean tissue or filter paper.
Rinse the electrode again with your test solution if possible forthe best result. Never rub the sensor.
4. Insert the electrode into your sample solution and stir it for a few seconds in the solution to remove
potential air bubbles. Then wait for the stable reading and take the measurement.
5. After measurement, insert the electrode back into the storage cap and twist it on. If the water in
the cap is contaminated, rinse out the storage cap and fill in new deionized or distilled water.
How to Maintain the Electrode
1. Always rinse the electrode with distilled or deionized water before and after each test and
calibration.
2. For organic residues, rinse the electrode with warm detergent water; For calcium and magnesium
sediments, use 10% lemon acid to clean them off.
3. Store the electrode in the storage cap filled with distilled or deionized water when not in use.
4. Keep the electrode connector clean and dry. Use cotton balls with isopropyl alcohol to clean if it
gets dirty and then blow-dry it. This is to prevent a potential short circuit, which will undermine
the electrode’s performance.
