MAINTENANCE

6.  MAINTENANCE

Electrode Care & Maintenance

Proper care and maintenance of the pH probe is essential for accurate readings. Cleaning, calibrating, 
and appropriate storage will extend the life of the probe.
Remove the electrode protective cap. Do not be alarmed if any salt deposits are present, this is normal. 
Rinse the probe with water.
Shake the electrode down as you would do with a clinical thermometer to eliminate any air bubbles 
inside the glass bulb (pH electrode only).
If the bulb and/or junction are dry, soak the electrode in 

HI703004

 or 

HI80300

 Storage solution for 

a minimum of 30 minutes. Rinse with water.
Calibrate before using.
When the electrode is not in use, add a few drops of 

HI703004

 Storage solution to the protective cap 

and replace the cap. To ensure a quick response, the glass bulb (pH electrode) and the junction should 
be kept moist and not allowed to dry out. 

Note:

 Never store the electrode in distilled or deionized water.

Refillable electrodes

If the electrolyte is more than 2 1/2 cm (1”) below the fill hole, add 

HI7082

 or 

HI8082

 3.5M KCl 

Electrolyte Solution (double junction) or 

HI7071

 or 

HI8071

 3.5M KCl+AgCl Electrolyte Solution 

(single junction electrodes).
For faster response, unscrew the fill hole screw during measurements.

AmpHel

®

 electrodes

If the electrode does not respond to pH changes, the battery is depleted and the electrode should be 
replaced.

General Maintenance

After prolonged storage or cleaning, calibration is required.
After use, rinse the probe with tap water and dry it. The pH electrode bulb must be kept moist.
Inspect the electrode and connection cable for scratches or cracks. The cable insulation and electrode 
bulb must be intact. 
Rinse the sensor in flowing water then clean by soaking it for 1 minute in 

HI70670

 Cleaning solution 

for mineral deposits or 

HI70671

 Cleaning & disinfection solution for algae, fungi and bacteria. 

After cleaning, soak the sensor in 

HI703004

 Storage solution for 30 minutes before calibrating.

pH refillable probes

Refill the reference chamber with fresh electrolyte (

HI7071

 or 

HI8071

 for single junction or 

HI7082

 or 

HI8082

 for double junction electrodes). Allow the electrode to stand upright for 1 hour.
