Reducing pretreatment: immerse the electrode for a few min-

utes in HI 7091.

Oxidizing pretreatment: immerse the electrode for a few min-

utes in HI 7092.

If the pretreatment is not performed, the electrode will take

significantly longer to respond.

As with pH electrodes, gel-filled redox electrodes are more

suitable for industrial applications due to lesser mainte-

nance requirements. However, if working with refillable

electrodes, the electrolyte level should not fall more than

2½ cm (1") below the fill hole and topped up if necessary.

Use HI 7071 refill solution for single junction and HI 7082

for double junction electrodes.

In the event that measurements are performed with solutions

containing sulfides or proteins, the cleaning of the diaphragm

of the reference electrode must be performed more often to

maintain the proper functioning of the ORP electrode. There-

fore, immerse it into HI 7020 and measure the response; the

obtained value should be within 200 and 275 mV.

After this functional test, it is suggested to wash the electrode

thoroughly with water and proceed to the oxidizing or reduc-

ing pretreatment before taking measurements.

When not in use, the electrode tip should be kept moist and

far from any type of mechanical stress which might cause

damage. This can be achieved by installing the electrode in

such a way that it is constantly in a well filled with the sample

(stream or tank). When not in use, store the electrode with a

few drops of HI 70300 storage solution in the protective

cap.

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 elec-

trode to see if the problem is alleviated.
