Probe Description; General Maintenance - Spectrum Technologies FieldScout 2127WE Manual

Place the probe onto the adapter with the logo facing up. It can take up to 30 seconds before the LED of the probe
indicates the status. It shows a red, pulsating light when charging up to 80%. The light changes to pulsating green when the
battery level is >80%. When the probe is removed from the charger, the LED will turn off.

•
Thee probes are used to monitor either pH only or pH/EC/ORP in soil.
•
The sensor is prone to scratches in this application
•
Use the predrill stick included to make a pilot hole in the soil you are testing
•
If the soil is dry, fill the hole with distilled water
•
When using the probe with semi-solids, insert the probe to the desired depth then rotate left and right several times
and tilt to ensure the sensor and diaphragm are in good contact with the sample
Preparing for Use
•
Unpack the probe and remove the dust cap. Flush the probe with distilled water. The probe is now ready for
calibration. When the probe has been stored for longer time, clean the probe as described below.
Cleaning
•
Place the probe in warm tap water (around 60°C / 140°F) with a mild detergent for 5 minutes. Stir periodically.
Soaking the probe first helps prevent scratching. Scrub the probe tip with a soft brush and water with a mild
detergent. After scrubbing, rinse with distilled water.
Revitalizing the Probe
•
When the probe shows slow response or low slope values, a revitalization of the reference should be performed.
Place the probe (still warm from cleaning) in a saturated KCl solution for 20 minutes at room temperature.
Storage
Short Term
•
Rinse the probe in distilled water, do not dry the probe. Place the probe in a clean beaker with fresh pH7 buffer to
prevent pollution of the probe after cleaning.
Long Term
•
Rinse the probe in distilled water, do not dry the probe. Place one drop of pH7 buffer in the dust cap and place the
cap over the probe tip. Store the probe in a safe place.
CHARGE THE PROBE
