•  No Slope: 

  -  Check the electrode for cracks in glass stem or bulb 

(replace the electrode if cracks are found).

  -  Make sure cable and connections are not damaged 

nor lying in a pool of water or solution.

• Slow Response/Excessive Drift: soak the tip in 

HI7061

 

solution for 30 minutes, rinse thoroughly in distilled water 
and then follow the Cleaning Procedure above.

• For ORP electrodes: polish the metal tip with a lightly 

abrasive paper (paying attention not to scratch the surface) 
and wash thoroughly with water.

Note

  With industrial applications, it is always recommended to 

keep at least one spare electrode handy. When anomalies 
are not resolved with a simple maintenance, change the 
electrode (and recalibrate the controller) to see if the problem 
is alleviated.
