OPERATIONS

1. Press the electrodes’ ceramic tip into the soil.

2. Submerge the tip or the entire electrode into electrolyte.

3. Place a sponge soaked in electrolyte under the ceramic tip for dry soil conditions.

4. The ceramic tip assembly must be soaked in electrolyte until thoroughly saturated.

MAINTENANCE & STORAGE

Before Use:

1. The Ag/CI element must be cleaned in distilled water or mild detergent and rinsed in distilled water
prior to use.

2. Do not touch Ag/CI element after cleaning.

3. The Ag/CI element should soak in electrolyte for at least 15 minutes before use to stabilize readings.

After Use:

1. To ensure proper readings we recommend the Ag/CI element and the ceramic tip assembly be kept
moist during storage. A solid body tube and protective cover are enclosed for this period as well as
for use in soil readings.

2. For long term storage disassemble or for use after element and ceramic tip have been allowed to dry
follow instructions above “Before Use”.
