The electrode used for the first time or long time without using,please immersing the electrode bulb and sand core into 3NKCL activation solution for 8 hours.
Keeping the electrode plug clean and dry.
The external reference solution is 3NKCL
Avoiding cross contamination between the solution when testing,just in case that influencing the accuracy for the test.
Polluted electrode bulb or wick will lower the PTS,therefore appropriate solution cleaning will restore the electrode performance.
Avoid to immerse the electrode into an acidic fluoride solution in a long-term.
Please remove the rubber band on the ceramic sand core and dosing port to maintain the speed of the salt bridge solution.
