Replacement Electrode for pH50

Replacement Probe for the pH50. 

Because it has a glass electrode that needs to constantly stay wet we recommend that you do not order it until you need it. 


To replace this part on your pH50 twist the grey ring located next to the cap. Twist until the you can easily remove the ring. Gently pull the area under where the ring was located. This is the electrode part. This will remove your old electrode. Put the old electrode somewhere else so you do not mix the two. Your new replacement electrode has two notches a large one and a small one. Line the notches up with the protruding lines in the meter. Gently push the replacement electrode so that the black seal is touching the meter. Take the grey ring you removed and put it back onto the meter by twisting it back on. Make sure you firmly twisted it to form a complete seal.
