Reactivating the pH electrode  

If stored and cleaned properly, your pH electrode should be ready for immediate use. However, a 
dehydrated bulb may cause sluggish response. To rehydrate the bulb, immerse the electrode in a pH 
4 buffer solution for 10 to 30 minutes. If this fails, the electrode requires activation. Never touch or 
rub glass bulb. Contact builds up an electrostatic charge.  

 

pH electrode activation (for glass body electrodes only) 

WARNING

: Only qualified persons proficient with the safe handling of dangerous chemicals should 

perform the procedure below. Provide proper containers, fume hoods, ventilation, and waste 
disposal. Safety goggles and protective clothing must be worn while performing this procedure. If 
possible, replace with another electrode instead of performing this re-activation procedure.  

1. 

Dip or stir the pH electrode in alcohol for 5 minutes.  

2. 

Leave the electrode in tap water for 15 minutes.  

3. 

Dip and stir the electrode in concentrate acid (such as HCL or H

2

SO

4

) for five minutes.  

4. 

Repeat Step 2.  

5. 

Dip and stir in strong base (NaOH) for five minutes.  

6. 

Leave for 15 minutes in tap water.  

7.  Now test with standard calibration buffer solutions to see if the electrode yields acceptable 

results. You may repeat step 3 through 6 up to three times for better response. If the response 
does not improve, then your electrode is no longer functioning. Replace with a new electrode – 
call your distributor for information.
